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.
Found and corrected via:
git ls-files | xargs sed --follow-symlinks -i 's/ ,d/, d/g'

The armv8a tune specific PACKAGE_EXTRA_ARCHS contained tune feature
names like "crc" and "crypto" rather than package architecture names
like "armv8a-crc" and "armv8a-crypto".

SIMD instructions are a mandatory part of armv8a
(they were optional in armv7a), and the gcc docs
also say that they are always enabled.

For multilib to work correctly, BASE_LIB overrides must be provided for
each new tune added in this file.

There are some addtional instructions apart from bare armv8,
also there is armv8.1, armv8.2.
Most the processor would support crc, except X-gene 1.
