commit e91c652af21557698751c3944ceb7c46e5e58164

    pylibfdt: Enable installation of Python module
    
    Adjust the setup script to support installation, and call it from the
    Makefile if enabled. It will be disabled if we were unable to build the
    module (e.g. due to swig being missing), or the NO_PYTHON environment
    variable is set.
