8.2.0: drop libstdc++ libking against libvtv

libstdc++ itself provides weak symbols to work
both against present and missing libvtv. Final
binary desides whetned to use vtv or not by
linking against libvtv.

The change drops libvtv RPATH=${build_dir} injection.

+Final libstdc++.so should not contain rpath to make libvtv usable.
+It's up to final binaries to link against proper libvtv.
