The unified syscall stuff is currently broken (not that it ever worked
for anything other than i386).  It wouldn't take much to fix it, but I
don't have time to deal with it at the moment.

Fixing it for non-PIC is easy.  Fixing it for PIC is more involved, and
the best approach to take isn't clear.

Even if it were working, I'd have to agree that the usefulness of the
unified syscall stuff is questionable _as_currently_implemented_.  There
are some tests I want to run (when I have time) to test out some ideas
for the PIC shared lib case.
