    Silence xsltproc when writing manpages
    
    Unless make is invoked with V=1, have xmlto pass the parameter
    'man.output.quietly=1' to xsltproc to suppress "Note: Writing foo.N"
    output from the manpages stylesheet.
    
    (This doesn't quite do what it says: The output is not silenced if V has
    any value, including 0.  You could consider that either a bug or a
    feature.)
