commit 1522cf05c9c3e9afd3ef9c7f3f419460c41488d9

    aclocal.m4: allow more GNU/Hurd tuples
    
    Running plain ./configure fails on hurd because
    ./config.guess reports unrecognised tuple:
        $ ./config.guess
        i686-unknown-gnu0.9
    
    The change makes the following target configure:
    $ ./configure --target=i686-unknown-gnu0.9
