d180cb9850 cc-wrapper: make machine configuration configurable
It is useful to make these dynamic and not bake them into gcc. This
means we don’t have to rebuild gcc to change these values. Instead, we
will pass cflags to gcc based on platform values. This was already
done hackily for android gcc (which is multi-target), but not for our
own gccs which are single target.

To accomplish this, we need to add a few things:

- add ‘arch’ to cpu
- add NIX_CFLAGS_COMPILE_BEFORE flag (goes before args)
- set -march everywhere
- set mcpu, mfpu, mmode, and mtune based on targetPlatform.gcc flags

cc-wrapper: only set -march when it is in the cpu type

Some architectures don’t have a good mapping of -march. For instance
POWER architecture doesn’t support the -march flag at all!

ac491d2df7 systems: remove android armv5te platform
this isn’t useful any more because the ndk we use no longer supports it.

589c2c2870 androidndk: fixup mess
New android ndk (18) now uses clang. We were going through the wrapper
that are provided. This lead to surprising errors when building.
Ideally we could use the llvm linker as well, but this leads to errors
as many packages don’t support the llvm linker.
