The patch below enables AIX thread support provided by aix-thread.c.
I'll wait a few days for objections before committing it.
* Makefile.in (rs6000-nat.o): Update dependencies.
From Nicholas Duffek:
* Makefile.in (ALLDEPFILES): Add aix-thread.c.
(aix-thread.o): New rule.
* configure.host (gdb_host): Set to aix432 on AIX 4.3.2+.
* config/powerpc/aix432.mh: New file.
