Thanks.  That's a lot of work.

#ifdef _AIX is more or less verboten in GCC code, so I rewrote that
into a configure-time test for whether loadquery was available, much
as the ELF code does a configure-time test for dl_iterate_phdr.  I
didn't test it on AIX, so let me know if I messed something up.

Committed as follows.

* configure.ac: Check for XCOFF32/XCOFF64.  Check for loadquery.
* filetype.awk: Separate AIX XCOFF32 and XCOFF64.
* xcoff.c: Add support for AIX XCOFF32 and XCOFF64 formats.
* configure, config.h.in: Regenerate.
