Are you sure this will actually enable the test on OS X 10.6?

hydric:~ mseaborn$ python -c 'import platform; print platform.architecture()'
('64bit', '')

The env var VERSIONER_PYTHON_PREFER_32_BIT is supposed to work but I've not got
it to work.

"arch -arch i386 python" should work.  See
native_client/src/trusted/python_bindings/build.scons.

However, IIRC platform.architecture() can be wrong, because it checks the
executable, which is fat (multiarch) on Mac OS X 10.6.

Please spell out the cases:
 * Mac OS X 10.5 bots have 32-bit Python 2.5 installed as part of the OS.
 * Mac OS X 10.6 bots have had 32-bit Python 2.5 manually installed.
