With this option one can set the default library to use if no `-stdlib=` is provided on compiler invocation (currently hard coded `libstdc++` which remains default)
Also add explicit option `-stdlib=libstdc++` to tests that require it and would fail when you choose `libc++`.

I haven't touched autotools which should be removed soon anyway. I'm fine if either someone else looks into it or if the patch only gets accepted afterwards.
