It doesn't need to be a separate patch, but could you add a note to
commit message about dropping RVCT support?
> + GCC:*_*_*_CC_FLAGS = -fno-lto -ffreestanding -Wno-unused-label
Hmm. You add -ffreestanding here, but you also add it to the CLANG
profiles in 4/7. Could we do one of:
- dropping this one, adding -ffreestanding to GCC profiles too in 4/7
- keeping this one, dropping the -ffreestanding from 4/7?
