c_args are meant to be overridden by the user if needed (even via the
environment CFLAGS variables + -Doptimization=plain, for example),
so they should not contain any option that affect the multilib search
path. For example, a hypothetical native file like this:
[binaries]
c = gcc
[built-in options]
c_args = ['-m32']
would *not* build 32-bit binaries if -Dc_args is passed to meson.
Such options, instead should be in the [binaries] section. Adjust
the sample cross files included with meson.

* Add preliminary support for the CompCert C Compiler
The intention is to use this with the picolibc, so some GCC flags are
automatically filtered. Since CompCert uses GCC is for linking, those
GCC-linker flags which are used by picolibc, are automatically prefixed
with '-WUl', so that they're passed to GCC.

add CompCert to meson (does not fully work, yet)
* remove unused import and s/cls/self/
fixes the two obvious LGTM warnings
* CompCert: Do not ignore unsupported GCC flags
Some are safe to ignore, however, as per
https://github.com/mesonbuild/meson/pull/7674, they should not be
ignored by meson itself. Instead the meson.build should take care to
select only those which are actually supported by the compiler.
* remove unused variable
* Only add arguments once.
* Apply suggestions from code review

* Remove erroneous ' ' from '-o {}'.format()
As noticed by @dcbaker
* added release note snippet for compcert
* properly split parameters
As suggested by @dcbaker, these parameters should be properly split into multiple strings.
Co-authored-by: Dylan Baker <dylan@pnwbakers.com>
* Update add_compcert_compiler.md
Added a sentence about the state of the implementation (experimental); use proper markdown
* properly separate arguments
