As we are talking hacks here anyway...

Edit your installed sipconfig.py and change the value of 'platform' in
_pkg_config to 'macx-clang-32'. Then back out all your related changes to
PyQt's configure.py.

In PyQt's new build system (4.10.1 hopefully) you will just be able to
pass --spec macx-clang-32 to its configure.py.
