This looks similar (or part of) the general "non default driver"
problem. We would like for clang to behave like the system compiler by
default, but it should be possible to support things like using a
libstdc++ installed in a different directory or a target a particular
cpu by default.
Unfortunately, there is very little support for that in the driver right
