Also note that python-config is itself a Python script that uses 
sysconfig and includes code like this:

     elif opt in ('--includes', '--cflags'):
         flags = ['-I' + sysconfig.get_path('include'),
                  '-I' + sysconfig.get_path('platinclude')]

So this would just do the same thing we are already doing anyway.
