This is just a small change in the Flang tool within libclangDriver.
Currently it passes `-triple` when calling `flang-new -fc1` for various
driver Jobs. Eventually these Jobs will require a triple, but currently
Flang doesn't support code-generation. As a consequence, `flang-new
-fc1` doesn't support `-triple.`

This hasn't been a problem as the affected Jobs aren't implemented or
used. However, we will be adding support for them in the near future.
However, while there is no code-generation, `-triple` is not required
and should remain unsupported.
