I need to add files compiled with an extra option,
e.g. -mexpand-mul (yeah, it's sort of libgcc1, but libgcc1 does
not work for cross and it's only multilibbed for asm anyway).

The rest of libgcc2 must not be compiled with that flag.
So it's *added* options rather than *other* options.

Is there another (simpler) way?
