[PATCH 2/2] kbuild: remove cc-option test of -ffreestanding

2020-06-26 Thread Masahiro Yamada
Some Makefiles already pass -ffreestanding unconditionally. For example, arch/arm64/lib/Makefile, arch/x86/purgatory/Makefile. No problem report so far about hard-coding this option. So, we can assume all supported compilers know -ffreestanding. I confirmed GCC 4.8 and Clang manuals document this
