    Fix for issue #7724: ensure that distutils and python's own setup.py
    honor the MacOSX SDK when one is specified.

    This is needed to be able to build using the 10.4u SDK while running
    on OSX 10.6.

    This is a fixed version of the patch in r80963, I've tested this patch
    on OSX and Linux.
