Yes, I think it's appropriate for 4.7.1 if all the follow-ups are backported as
well.  I'll give it a whirl on SPARC.

I think I have included them all in the patch I attached.  Meanwhile
multilib testing has finished on x86_64, a pure i?86 bootstrap still
pending (I'm also testing on arm and ppc/ppc64 now, but that may
take a while)
