    Filename suffix for shared libraries is defined in pep-3149.  The
    pep claims to only address posix systems, but the recommended
    sysconfig.get_config_var('EXT_SUFFIX') also seems to give the
    right string on Windows.
    
    If use_so_versioning is false, we return only the last component of
    the suffix, which removes any version number, for example changing
    `.cp312-win_amd64.pyd` to `.pyd`.

    #   openbsd:    .cpython-310.so
