    gnu: python: Support native build on the Hurd.
    
    Running "test_concurrent_futures" and "test_venv" freeze the Hurd.  Tests
    "test_multiprocessing_forkserver" and "test_multiprocessing_spawn" run over
    10mins. Debian simply skips all tests on the Hurd.
    
    * gnu/packages/python.scm (python-3.10)[arguments]: When building for the
    Hurd, add hanging and failing to #:make-flags's --exclude flag.  Also, add
    'disable-multi-processing' phase to avoid compileall.py hang during install.
