Either way is fine for me. Simon did separate symbols in his
nios2 patch[1], and I don't mind staying with that version
unless someone else feels strongly about it.

I would however like to have separate patches to add lib/divmul.c
and lib/mulsi3.c, and then patches on top that start using these
from nios2 and arc.
