Python normally chooses those -arch flags which were chosen for Python
at compile time.
It's not a good idea to set CFLAGS and LDFLAGS with distutils I
learned. They do not stack with the compilation time CFLAGS etc., but
completely override. Better adapt the pathes in setupext.py.

So we should team up in improving our docs :-)
