From: Nathan Chancellor <nathan@xxxxxxxxxx>
commit 337ff6bb8960fdc128cabd264aaea3d42ca27a32 upstream.
A future change will switch as-option to use KBUILD_AFLAGS instead of
KBUILD_CFLAGS to allow clang to drop -Qunused-arguments, which may cause
issues if the flag being tested requires a flag previously added to
KBUILD_CFLAGS but not KBUILD_AFLAGS. Use cc-option for cflags additions
so that the flags are tested properly.
