    python path: work around a bug in a Fedora patch
    
    The Fedora python package patches the get_python_lib() function in
    distutils.sysconfig, breaking its API by returning different values,
    depending on plat_specific, even if prefix is given.
    
    See https://bugzilla.redhat.com/show_bug.cgi?id=1076293.
    
    Work around that by checking for the different path and adding it to the
    path as well.
