21.2 startup crash on Irix

[Dave Love]

This crash happens reading my .emacs with both a cc and gcc build of
Emacs 21.2 on Irix 6.5.15m + development utilities 7.3.  It doesn't
happen if I isolate the code fragment that triggers it, and I guess
it's just a symptom of lossage elsewhere that I can't track down
immediately.  It doesn't happen with 21.1 newly built in the same
circumstances.

[Reverting the dubious-looking changes to unexelf.c for .got sections
doesn't help, but I don't see how that would be correct and it's not
necessary on any of the versions I've tested Emacs on for several
years.]
