Fix a bug in build_externals, it wasn't updating PYTHONPATH

Fix a bug in build_externals, it wasn't updating PYTHONPATH so the
launched python processes to run setup.py and such were not seeing the
site-packages directory.  This prevented matplotlib from seeing the
just built and installed numpy module.

This bug was introduced when the 'import common' was added to this
module as that already inserted site-packages into sys.path.
