    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 "test_concurrent_futures", "test_venv",
    "test_multiprocessing_forkserver", "test_multiprocessing_spawn",
    "test_builtin", "test_capi", "test_dbm_ndbm, "test_exceptions",
    "test_faulthandler", "test_getopt", "test_importlib", "test_json",
    "test_multiprocessing_fork", "test_multiprocessing_main_handling", 
"test_pdb",
    "test_sqlite, and "test_regrtest" to #:make-flags's --exclude flag.  Also, 
add
    'disable-multi-processing' phase to avoid compileall.py hang during install.
