Its sad we need to do this but do_install and do_populate_sysroot appear
to change the files in ${B} and this breaks if something works in parallel
like gcc_stash_builddir. We've seen a few too many race errors on the
autobuilder which appear to be from this so make things run in sequence
deterministically for now.
An example failure was this from do_populate_sysroot whilst stash_builddir was running

Currently there is a race where if you build -cross-canadian without building gcc (target)
you see QA errors about RPATHS. I've tracked this down to this manipulation where the
target gcc recipe changes libcc1 in the shared sources directory. As long as you build
things in the right order, the problem doesn't occur.
Since its changing ${S} move it to gcc-source and avoid the race, saving RP

When we stashed the gcc build directory for use in generating the various runtimes
we were being lazy and just used the staging directory. With recipe specific
sysroots this means we're copying a large chunk of data around with the cross
compiler which we don't really need in most cases.
Separate out the data into its own task and inject this into the configure
step. We have to do that here since autotools will wipe out ${B} if it thinks
we're rebuilding and we therefore have to time its recreation after that.
This also takes the opportunity to remove some pointless (as far as I can tell)
conditionals from the do_install code.

This patch is comparatively large and invasive. It does only do one thing, switching the
system to build using recipe specific sysroots and where changes could be isolated from it,
that has been done.
With the current single sysroot approach, its possible for software to find things which
aren't in their dependencies. This leads to a determinism problem and is a growing issue in
several of the market segments where OE makes sense. The way to solve this problem for OE is
to have seperate sysroots for each recipe and these will only contain the dependencies for
that recipe.
Its worth noting that this is not task specific sysroots and that OE's dependencies do vary
enormously by task. This did result in some implementation challenges. There is nothing stopping
the implementation of task specific sysroots at some later point based on this work but
that as deemed a bridge too far right now.
Implementation details:
* Rather than installing the sysroot artefacts into a combined sysroots, they are now placed in
TMPDIR/sysroot-components/PACKAGE_ARCH/PN.
* WORKDIR/recipe-sysroot and WORKDIR/recipe-sysroot-native are built by hardlinking in files
from the sysroot-component trees. These new directories are known as RECIPE_SYSROOT and
RECIPE_SYSROOT_NATIVE.
* This construction is primarily done by a new do_prepare_recipe_sysroot task which runs
before do_configure and consists of a call to the extend_recipe_sysroot function.
* Other tasks need things in the sysroot before/after this, e.g. do_patch needs quilt-native
and do_package_write_deb needs dpkg-native. The code therefore inspects the dependencies
for each task and adds extend_recipe_sysroot as a prefunc if it has populate_sysroot
dependencies.
* We have to do a search/replace 'fixme' operation on the files installed into the sysroot to
change hardcoded paths into the correct ones. We create a fixmepath file in the component
directory which lists the files which need this operation.
* Some files have "postinstall" commands which need to run against them, e.g. gdk-pixbuf each
time a new loader is added. These are handled by adding files in bindir with the name
prefixed by "postinst-" and are run in each sysroot as its created if they're present.
This did mean most sstate postinstalls have to be rewritten but there shouldn't be many of them.
* Since a recipe can have multiple tasks and these tasks can run against each other at the same
time we have to have a lock when we perform write operations against the sysroot. We also have
to maintain manifests of what we install against a task checksum of the dependency. If the
checksum changes, we remove its files and then add the new ones.
* The autotools logic for filtering the view of m4 files is no longer needed (and was the model
for the way extend_recipe_sysroot works).
* For autotools, we used to build a combined m4 macros directory which had both the native and
target m4 files. We can no longer do this so we use the target sysroot as the default and add
the native sysroot as an extra backup include path. If we don't do this, we'd have to build
target pkg-config before we could built anything using pkg-config for example (ditto gettext).
Such dependencies would be painful so we haven't required that.
* PKDDATA_DIR was moved out the sysroot and works as before using sstate to build a hybrid copy
for each machine. The paths therefore changed, the behaviour did not.
* The ccache class had to be reworked to function with rss.
* The TCBOOTSTRAP sysroot for compiler bootstrap is no longer needed but the -initial data
does have to be filtered out from the main recipe sysroots. Putting "-initial" in a normal
recipe name therefore remains a bad idea.
* The logic in insane needed tweaks to deal with the new path layout, as did the debug source
file extraction code in package.bbclass.
* The logic in sstate.bbclass had to be rewritten since it previously only performed search and
replace on extracted sstate and we now need this to happen even if the compiled path was
"correct". This in theory could cause a mild performance issue but since the sysroot data
was the main data that needed this and we'd have to do it there regardless with rss, I've opted
just to change the way the class for everything. The built output used to build the sstate output
is now retained and installed rather than deleted.
* The search and replace logic used in sstate objects also seemed weak/incorrect and didn't hold
up against testing. This has been rewritten too. There are some assumptions made about paths, we
save the 'proper' search and replace operations to fixmepath.cmd but then ignore this. What is
here works but is a little hardcoded and an area for future improvement.
* In order to work with eSDK we need a way to build something that looks like the old style sysroot.
"bitbake build-sysroots" will construct such a sysroot based on everything in the components
directory that matches the current MACHINE. It will allow transition of external tools and can
built target or native variants or both. It also supports a clean task. I'd suggest not relying on
this for anything other than transitional purposes though. To see XXX in that sysroot, you'd have
to have built that in a previous bitbake invocation.
* pseudo is run out of its components directory. This is fine as its statically linked.
* The hacks for wayland to see allarch dependencies in the multilib case are no longer needed
and can be dropped.
* wic needed more extensive changes to work with rss and the fixes are in a separate commit series
* Various oe-selftest tweaks were needed since tests did assume the location to binaries and the
combined sysroot in several cases.
* Most missing dependencies this work found have been sent out as separate patches as they were found
but a few tweaks are still included here.
* A late addition is that extend_recipe_sysroot became multilib aware and able to populate multilib
sysroots. I had hoped not to have to add that complexity but the meta-environment recipe forced my
hand. That implementation can probably be neater but this is on the list of things to cleanup later
at this point.
In summary, the impact people will likely see after this change:
* Recipes may fail with missing dependencies, particularly native tools like gettext-native,
glib-2.0-native and libxml2.0-native. Some hosts have these installed and will mask these errors
* Any recipe/class using SSTATEPOSTINSTFUNCS will need that code rewriting into a postinst
* There was a separate patch series dealing with roots postinst native dependency issues. Any postinst
which expects native tools at rootfs time will need to mark that dependency with PACKAGE_WRITE_DEPS.
There could well be other issues. This has been tested repeatedly against our autobuilders and oe-selftest
and issues found have been fixed. We believe at least OE-Core is in good shape but that doesn't mean
we've found all the issues.
Also, the logging is a bit chatty at the moment. It does help if something goes wrong and goes to the
task logfiles, not the console so I've intentionally left this like that for now. We can turn it down
easily enough in due course.

Arm is unusual in that we force it to "linux-gnueabi" and "linux" doesn't
build. This was causing problems for multilib configurations which were assuming
"linux" was the default compiler rather than linux-gnueabi.
This change does two things, ensures symlinks are generated for linux-gnueabi
and also adapts the libgcc code to account for the difference on arm.
It still needs to immediately expand/save TARGET_VENDOR but we defer
deciding what TARGET_OS should be until we know TARGET_ARCH (which the
multilib code may change).

We explicitly set the hash style to gnu in our LDFLAGS. Setting the default to
this in the toolchain, while convenient, actually hides bugs, as a failure to
obey LDFLAGS isn't noticed. By removing this, it's not dissimilar to how we
poison the sysroot -- rather than relying on the default, notice right away if
somoeone isn't obeying the needed flags.
This will result in a failure to obey LDFLAGS causing a GNU_HASH QA failure,
which is what's often seen with external toolchains. This brings us all on the
same page, and makes sure a failure to obey LDFLAGS is seen early.
This is limited to cross, to retain ease of use for SDKs.

In order to use certain features of gcc, you need the corresponding

default when installing the compiler since they are required if certain
command line options are used, so add them to RRECOMMENDS. I used
RRECOMMENDS since some of these packages may or may not exist depending
on architecture and build options; additionally it makes it possible to
use BAD_RECOMMENDATIONS if you really want to exclude them.
The impact of this isn't too bad in the context of an image providing
