distutils' sysconfig.py was patched in 2.7.3 without paying too
much attention to breaking things.

mxSetup doesn't use the distutils sysconfig.py module, but has it's
own way of configuring the compiler on Unix platforms (one which allows
for more flexibility in overriding setting using environment variables).

I guess we could change this to use distutils' sysconfig.py for Python 2.7.3,
but if you look at this patch on the ticket:
http://bugs.python.org/file26105/issue13950-version3.patch
you'll see that the sysconfig.py patching is likely going to be
removed again in 2.7.4.

The better way to do all this is using environment variables. Set CC to
your compiler as mentioned on the bug message and things should work
(now and also for 2.7.4).
