--- Comment #4 from Richard Earnshaw <rearnsha at gcc dot gnu.org> --- You're going to need --with-multilib=aprofile,rmprofile if you want the full set of multilibs. But beware it builds a *lot* of them. We don't enable this by default because it conflicts with --with-arch, --with-cpu and --with-float configure options. Describing how to pick the right multilib when there are so many to chose from is just too complex to describe when the base architecture isn't nailed down.
