    build: shorten macro references
    
    Presumably by copy-and-paste we've accumulated a number of instances of
    $(@D)/$(@F), which really is nothing else than $@. The split form only
    needs using when we want to e.g. insert a leading . at the beginning of
    the file name portion of the full name.
