Easy to reproduce with a .c file that has a single line:
non_existing_macro(xxx);
Apparently that's due to the -w option in arch/powerpc/math_emu/Makefile:
ccflags-y = -w
Was introduced by commit d2b194ed8208 ("powerpc/math-emu: Use kernel generic math-emu code")
If I understand correctly it means 'ignore all warnings'. Then it seems CLANG doesn't honor that request.
