    tools/automake: move file requirements to higher strictness
    
    GNU standards requires certain files at the top-level directory
    of a package that automake is used with, mostly documentation.
    
    If one of these files happens to be missing, autoreconf would fail.
    
    Move these file requirements to the more strict 'GNITS' setting.
