GCC has the ability to pass extensions to the march parameter, which
expand the funcationality of the march. For example
"-march=armv7ve+simd" adds SIMD to ARMv7. Currently, there is no way to
expand the march setting without modifying each instance, as you can't
guarantee the ordering when using the existing TUNE_CCARGS. By
introducing two new variables, TUNE_CCARGS_MARCH and
TUNE_CCARGS_MARCH_OPT, we can enforce that these two go together.
Also, expand existing and create new feature files that use these
variables to expand the functionality.

This is the result of automated script conversion:
scripts/contrib/convert-overrides.py <oe-core directory>
converting the metadata to use ":" as the override character instead of "_".

Multiple files have " ," instead of ", " in expressions. This changes
them to conform to the way the rest of them are done.

-march=armv5't'e means that CPU can execute thumb ISA, we do not need to
tie this to exclusively generating thumb ISA, this change means that
when we have thumb in tune features then it can use 't' in -march
options irrespective of ISA being thumb or arm.
This fixes derivative of armv5 tunes and paves way for gcc9 where e.g.
armv5e is dropped and minimum arch supported is armv5te

* respect missing "arm" in TUNE_FEATURES in feature-arm-thumb.inc, so

recipe and try to build with "thumb"
* show warning when overriding ARM_INSTRUCTION_SET set by recipe from tune

* number of TUNE_CCARGS conditionals is important if we add
extra space with each one in "else" branch
I'm building for 2 MACHINEs one is cortexa9, second is cortexa8
few months ago we added TUNE_CCARGS[vardepvalue] in bitbake.conf
http://git.openembedded.org/openembedded-core/commit/?id=03f1e34ea3ce80931e9c3cd2ab22824f28a7233b
which fixed some cases (like mentioned tune-xscale and tune-arm926ejs)
where both had unused TUNE_CCARGS when common DEFAULTTUNE was used.
with cortexa[89] it's different, because cortexa9 has one extra TUNE_CCARGS
TUNE_CCARGS += "${@bb.utils.contains("TUNE_FEATURES", "cortexa9", "-mtune=cortex-a9", "", d)}"
which adds extra *space* even when not used because of '+=' and as result:

OVERRIDES reads from left to right, least to most specific. We were
appending to MACHINEOVERRIDES when we should have been prepending so
the ordering of qemuall verses qemuxxx was incorrect, as was the x86
override and several of the arm overrides. This patch is a batch cleanup
of the various issues to correct the order from least to most specific.
The include order does matter and we needed to tweak some of that in this
patch too.

Cleanup the ARM tunings to match the new tunings README file.
The ARM tunings define TUNE_PKGARCH in a way that only one main
arm architecture, i.e. armv6, may be defined at the same time. We
may have to revise these settings in the future, as well as figure
out a way to better differentiate various optimize tunings in the
package arch. (This was not done, to preserve existing behavior!)
Fix a number of minor issues w/ the armv5 tunings where DSP variants
were referenced but not defined.
Fix incorrect armv7 entries in armv7a.
Fix PACKAGE_EXTRA_ARCHS definitions inside of tune-cortexm3 and tune-cortexr4.
