    Comment on BuildRoot not being required any more
    
    Comment on BuildRoot not being required any more, but keeping
    a BuildRoot definition for spec file robustness. Someone might
    build this spec file in a build environment where BuildRoot is
    (still) needed.
    
    Also change to the mkdir based BuildRoot definition.
