Christian Ehrhardt 9584d3d00a build: disable fcf-protection on -march=486 -m16
Some of the roms build with -march=i486 -m16 which is incompatible
with -fcf-protection. That in turn is can be set by default, for
example in Ubuntu [1].
That causes:
 cc1: error: ‘-fcf-protection’ is not compatible with this target

This won't work on -march=i486 -m16 and no matter if set or not we can
override it to "none" if the option is known to the compiler to be
able to build reliably.

Fixes: https://gitlab.com/qemu-project/qemu/-/issues/889
