I think there is unfortunately no better way of doing this at the moment,
except for changing Clang. The problem is that OpenMP might already be shipped
with the system, and then a lot of conflicts can happen if the wrong version of
the OpenMP target library or the device runtime is picked up. But I agree that
this is indeed not very user friendly and that it would be a lot nicer if Clang
automatically did this.
