AFAICT, we build shared libraries on AIX okay.

I'm not sure about this change.  $(python_libspec) is to link an embedded
python, e.g., it includes -lpython itself.  I'm not sure this would work
everywhere, since the module will be loaded by a python interpreter, so
you could get conflicts.  Does this correspond to what the current "gmake
all" gives you?

I have since found supporting documentation for this.
