Sorry, but I didn't mean you should change the message. My only point here is that I don't see the need for adding a new diagnostic, you can still keep something more similar with your old intent, example:

  D.Diag(diag::err_drv_clang_unsupported) << "C++ for target" << getToolChain().getTriple().str();
