David Edelsohn 47ddb895df aix: Add GCC64 configuration and FAT target libraries. 
This patch adds the ability to configure GCC on AIX to build as a
64 bit application and to build target libraries "FAT" libraries in both
32 bit and 64 bit mode.

The patch adds makefile fragment hooks to target libraries that allows
them to include target-specific rules.  The target specific rules for
AIX place both 32 bit and 64 bit objects and shared objects
in archives at the top-level, not multilib subdirectories.  The
multilibs are built in subdirectories, but must be combined during the
last parts of the target library build process.  Because of the way
that GCC bootstrap works, the libraries must be combined during the
multiple stages of GCC bootstrap, not solely when installed in the
final destination, so the libraries are correct at the end of
each target library build stage, not solely an install recipe.
