I don't know what's going on with this one, I don't actually see
a reason why it isn't already wired up on all architectures. If we add
this, it should probably be done for all architectures at once as a
bugfix, but it's possible that this is intentionally only used on
x86 and arm.

André, can you comment on this?

I've added entries for the archs that I've actually tested, but there
should not be any arch-specific problems in futex_waitv. I'll submit a
patch to wire it up for the remaining architectures.
