- Now `pkg.outputUnspecified = true` but this attribute is missing in every output, so we can recognize whether the user chose or not. If (s)he didn't choose, we put `pkg.bin or pkg.out or pkg` into `systemPackages`. - `outputsToLink` is replaced by `extraOutputsToLink`. We add extra outputs *regardless* of whether the user chose anything. It's mainly meant for outputs with docs and debug symbols. - Note that as a result, some libraries will disappear from system path.
