From: Nick Desaulniers <ndesaulniers@xxxxxxxxxx>
commit 994f5f7816ff963f49269cfc97f63cb2e4edb84f upstream.
as-option tests new options using KBUILD_CFLAGS, which causes problems
when using as-option to update KBUILD_AFLAGS because many compiler
options are not valid assembler options.
This will be fixed in a follow up patch. Before doing so, move the
assembler test for -Wa,-mrelax-relocations=no from using as-option to
cc-option.
