on a second thought, I think we don't care about this. Because we build
the objects in kbuild with make and not with gas directly. IOW, we never
use the intermittent product file.s when building file.o but we start
again from file.c.

And besides, even if we did use gas, we would still need to pass
KBUILD_AFLAGS to it.

Hmmm.
