commit 7628f6bdb5704c018d83e284364994b72557eaa5

    chrpath.bbclass: Add break_hardlinks kwarg to allow breaking hardlinks
    
    Add the break_hardlinks kwarg to break hardlinks when modifying files.
    This uses the bb.utils.break_hardlinks function to break hardlinks. The
    default is to maintain existing behaviour and leave hardlinks in place.
