Ok, a silly question...

That's good, but I think CC should be preserved too.

You might multilib on -mrtd or -mregparm=3 if you're building for x86, which
will definitely break things if they go wrong.  That's much less faked and,
to some extent, it might even be useful (but not in an unified tree, as it
will interact with assembly language files in newlib and BTW also in
libffi -- so no Java as well).

Which is great.
