Explicitly setting CFLAGS, AFLAGS, etc. like this will cause severe
misbehavior.  It overrides the composition of the flags at many
different points within the build and will cause unobvious lossage
that is hard to debug even when it does not cause an immediate
build-time explosion.  Don't ever do it.
