I hope so, but it needs to be reviewed by one or more senior build
gurus, before it makes a chance (if any) to get into 9.0-R.

It's really just a band-aid now.  Obviously, the whole way Makefile.inc1
sets up CC to run the build32 stage should be overhauled, and as Warner
said, we really need a (SYSTEM|WORLD|PORTS)_COMPILER global switch
(instead of manually setting CC), but that kind of restructuring must be
done after the tree is unfrozen, not now.
