   Is n64 as default a good choice? n32 provides better performance unless
   you exceed 2GB address space.

OpenBSD/mips64 only supports fully 64-bit code.

   Is mips-dec-openbsd* mentioned above it obsolete? I figure that's the
   pmax port you mentioned above.

Suppose so.  The current config.guess won't produce that triplet.  And
specifying that target by hand won't work either since that results in
an attempt to build an ELF gas with a BFD that only supports ECOFF.

I'll happily remove that config.
