Also .lit4 and .lit8.  Look at unexelf.c and unexsgi.c: one has suport
for SONY news with ELF, and the other has support for IRIX.
There's also some munging the debug information section, too.

I can't figure out what the differences are, ``right'' thing to do is,
and I dont really have time anymore.

Maybe #ifdef'ing the current unexalpha.c to be compilable for either
32-bit elf or 64-bit elf would be a better start?
