    devel/llvm21: don't build gold plugin when disabled
    
    Disabling the GOLD option didn't actually disable building the plugin,
    it just didn't install it in the package.  Actually stop traversing into
    the directory when the option disabled so we don't end up needing
    devel/binutils.
