When clang's -Qunused-arguments is dropped from KBUILD_CPPFLAGS, it warns that ASFLAGS contains '-s', which is a linking phase option, so it is unused. clang-16: error: argument unused during compilation: '-s' [-Werror,-Wunused-command-line-argument] Looking at the GAS sources, '-s' is only useful when targeting Solaris and it is ignored for the powerpc target so just drop the flag altogether, as it is not needed.
