Do we expect to have a lot of such new flags in the future? We already
do something similar for some of the arm specific flags (E.G. force
-marm for stuff that cannot be built in thumb2 mode).

I agree that it isn't very pretty, but again it is a tradeoff between
how complicated we want to make the toolchain wrapper.
