Partial support for cross-platform generation of bdist_wininst .exe's.

Unfortunately, bdist_wininst doesn't fix up #! lines, so python.exe or
pythonw.exe have to be on PATH for generated scripts to work.  This
could probably be fixed up with a post-install script, but that's a
job for another day.  (backport from trunk)
