    icons: fix gimp-toilet-paper icon exception.
    
    It was infinitely-looping because of a mis-usage of the % matching rule.
    On the rule or dependency side, I must use $(@D) instead of % to match
    the directory part of the target (I could also have used $* to get only
    the matching part of the stem).
