When clang's -Qunused-arguments is dropped from KBUILD_CPPFLAGS, it warns that KBUILD_AFLAGS_64 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] There appears to be no equivalent for '-s' in GNU as; 'as --help' on x86_64 notes that '-s' is ignored and 's390x-linux-gnu-as --help' makes no mention of it whatsoever. Just drop '-s' altogether, as it has been there since the introduction of the vDSO, which means it is likely uneeded, given there would likely have been a report by this point.
