[RFA] Update OpenBSD/mips64 support

[Mark Kettenis]

This makes gas work for the new 64-bit OpenBSD/sgi aka OpenBSD/mips64.
It's fairly obvious, except for the fact that it replaces an older
32-bit OpenBSD/mips config.  I don't think it's worth retaining that
config since the members of that family have been discontinued with
OpenBSD/arc 2.3 and OpenBSD/pmax 2.7.  The latter was released over 5
years ago.

Ok?
