This is basically reverting commit 3dd46c78525a30e98c68 from
2013, which explicitly switched to using separate CPP and
AS steps "because the C compiler could be unsuitable", by
which I think it means the failure described here:
https://lists.gnu.org/archive/html/qemu-devel/2013-01/msg00558.html
where if the compiler is clang it might not be able to
handle some of the code we use in the optionrom assembly
even though 'as' can.

Does that no longer apply ?
