distutils 'setup.py config' support for bsd.python.mk

[Mike Brown]

Python's distutils supports a config target for the setup.py script, in 
addition to build and install. That is, in order to build a python application,
one might have to do
  python setup.py config argfoo argbar
  python setup.py build argbaz
  python setup.py install argmaz

bsd.python.mk currently only supports build and install. Any chance a patch 
like the one below (untested) can go in?
