gcc: Update patches submitted/merged upstream

I took 5 of our patches and submitted to upstream gcc. This highlighted that
patches 0026 and 0018 should be merged together and some tweaks were made to
try and make it acceptable to upstream. The other patches have their headers
updated to match what was submitted.

The libstdc++ option patch was also cleaned up ready for upstream as the
documentation wasn't quite right.

The CXXFLAGS_FOR_BUILD piece of 0026 is separated out into a new patch which
can be submitted separately to upstream.

Two of the patches have been merged, status updated accordinly.

A "standard" gcc build uses xgcc and hence avoids this. We should ask upstream how to
do this officially, the likely answer is don't build libstdc++ separately.

OpenEmbedded/Yocto Project builds libgcc and the other gcc runtime libraries
separately from the compiler and slightly differently to the standard gcc build.
Signed-off-by: Khem Raj <raj.khem@gmail.com>
In general this works well but in trying to build them separately we run into
an issue since we're using our gcc, not xgcc and there is no way to tell configure
to use libgcc but not look for libstdc++.
Upstream-Status: Inappropriate [embedded specific]
This adds such an option allowing such configurations to work.

Subject: [PATCH] cpp: honor sysroot.
From: Richard Purdie <richard.purdie@linuxfoundation.org>
Subject: [PATCH 5/5] gcc: Pass sysroot options to cpp for preprocessed source
Currently, if the gcc toolchain is relocated and installed from sstate, then you try and compile
preprocessed source (.i or .ii files), the compiler will try and access the builtin sysroot location
rather than the --sysroot option specified on the commandline. If access to that directory is
permission denied (unreadable), gcc will error.
OpenEmbedded/Yocto Project extensively uses the --sysroot support within gcc.
We discovered that when compiling preprocessed source (.i or .ii files), the
compiler will try and access the builtin sysroot location rather than the
--sysroot option specified on the commandline. If access to that directory is
permission denied (unreadable), gcc will error. This is particularly problematic
when ccache is involved.
This happens when ccache is in use due to the fact it uses preprocessed source files.
This patch adds %I to the cpp-output spec macro so the default substitutions for
-iprefix, -isystem, -isysroot happen and the correct sysroot is used.
The fix below adds %I to the cpp-output spec macro so the default substitutions for -iprefix,
-isystem, -isysroot happen and the correct sysroot is used.

Subject: [PATCH] gcc: Fix argument list too long error.
From: Richard Purdie <richard.purdie@linuxfoundation.org>
Subject: [PATCH 2/5] gcc: Fix "argument list too long" from install-plugins
There would be an "Argument list too long" error when the
build directory is longer than 200, this is caused by:
When building in longer build paths (200+ characters), the
"echo $(PLUGIN_HEADERS)" from the install-plugins target would cause an
"argument list too long error" on some systems.
headers=`echo $(PLUGIN_HEADERS) | tr ' ' '\012' | sort -u`
Avoid this by calling make's sort function on the list which removes
duplicates and stops the overflow from reaching the echo command.
The original sort is left to handle the the .h and .def files.
The PLUGIN_HEADERS is too long before sort, so the "echo" can't handle
it, use the $(sort list) of GNU make which can handle the too long list
would fix the problem, the header would be short enough after sorted.
The "tr ' ' '\012'" was used for translating the space to "\n", the
$(sort list) doesn't need this.

Subject: [PATCH] export CPP
From: Richard Purdie <richard.purdie@linuxfoundation.org>
Subject: [PATCH 1/5] Makefile.in: Ensure build CPP/CPPFLAGS is used for build targets
The OE environment sets and exports CPP as being the target gcc. When
building gcc-cross-canadian for a mingw targetted sdk, the following can be found
in build.x86_64-pokysdk-mingw32.i586-poky-linux/build-x86_64-linux/libiberty/config.log:
During cross compiling, CPP is being set to the target compiler even for
build targets. As an example, when building a cross compiler targetting
mingw, the config.log for libiberty in
build.x86_64-pokysdk-mingw32.i586-poky-linux/build-x86_64-linux/libiberty/config.log
shows:
configure:3641: checking for _FILE_OFFSET_BITS value needed for large files
configure:3666: gcc -c -isystem/media/build1/poky/build/tmp/sysroots/x86_64-linux/usr/include -O2 -pipe conftest.c >&5
configure:3666: $? = 0
configure:3698: result: no
configure:3786: checking how to run the C preprocessor
configure:3856: result: x86_64-pokysdk-mingw32-gcc -E --sysroot=/media/build1/poky/build/tmp/sysroots/x86_64-nativesdk-mingw32-pokysdk-mingw32
configure:3876: x86_64-pokysdk-mingw32-gcc -E --sysroot=/media/build1/poky/build/tmp/sysroots/x86_64-nativesdk-mingw32-pokysdk-mingw32 conftest.c
configure:3856: result: x86_64-pokysdk-mingw32-gcc -E --sysroot=[sysroot]/x86_64-nativesdk-mingw32-pokysdk-mingw32
configure:3876: x86_64-pokysdk-mingw32-gcc -E --sysroot=[sysroot]/x86_64-nativesdk-mingw32-pokysdk-mingw32 conftest.c
configure:3876: $? = 0
Note this is a *build* target (in build-x86_64-linux) so it should be
using the host "gcc", not x86_64-pokysdk-mingw32-gcc. Since the mingw32
headers are very different, using the wrong cpp is a real problem. It is leaking
into configure through the CPP variable. Ultimately this leads to build
failures related to not being able to include a process.h file for pem-unix.c.
This is libiberty being built for the build environment, not the target one
(i.e. in build-x86_64-linux). As such it should be using the build environment's
gcc and not the target one. In the mingw case the system headers are quite
different leading to build failures related to not being able to include a
process.h file for pem-unix.c.
The fix is to ensure we export a sane CPP value into the build
environment when using build targets. We could define a CPP_FOR_BUILD value which may be
the version which needs to be upstreamed but for now, this fix is good enough to
avoid the problem.
Further analysis shows the same issue occuring for CPPFLAGS too.
RP 22/08/2013
Fix this by adding support for CPP_FOR_BUILD and CPPFLAGS_FOR_BUILD which
for example, avoids mixing the mingw headers for host binaries on linux
systems.

From cd5db101e3c4e72248f988a67ce28be8e24f66d4 Mon Sep 17 00:00:00 2001
From: Khem Raj <raj.khem@gmail.com>
Date: Mon, 7 Dec 2015 23:42:45 +0000
Subject: [PATCH] Fix various _FOR_BUILD and related variables
When doing a FOR_BUILD thing, you have to override CFLAGS with
CFLAGS_FOR_BUILD. And if you use C++, you also have to override
CXXFLAGS with CXXFLAGS_FOR_BUILD.
Without this, when building for mingw, you end up trying to use
the mingw headers for a host build.
The same goes for other variables as well, such as CPPFLAGS,
CPP, and GMPINC.
