This the build machinery on OSX to re-enable building (and installing)
PythonLauncher.app and IDLE.app.

This needs ports of fixes to Lib/distutils/util.py and Include/pymacconfig.h
to be fully functiontional, to be fully functional.

I also have a patch for Makefile.pre.in that I'll post on bugs.python.org
for review.

Removal of the Mac modules broke many of the Mac scripts (including
BuildApplet.py) so the building of the Python launcher and IDLE.app was
broken. I manually copied built versions of those apps into Mac. Everything else
which used Mac modules had to die.
