I tried bootstrap with AIX.  Because AIX static libstdc++ requires
libsupc++, the search path for that library in the build directory
needs to be on the link line.  Manually adding that directory allows
GCC on AIX to get through stage3 bootstrap.

There are two other problems / annoyances independent of AIX:

1) All of the multilibs for libstdc++ are configured and built during
bootstrap.  This always has been the case for libgcc, but it was not
as much of an inconvenience.

2) The Graphite CLooG headers are not C++-clean, so enabling Graphite
fails in CXX mode.
