@nico Please don't hesitate to ping me directly if I don't answer, I completely missed this review.
My memory is failing me (the commit was three years ago) and so I don't have a lot more to add.

I _think_ that some of the compiler we used back then was not printing the Target Triple with just `-v` and so we had to explicitly request `--version`. IIRC we used to use a machine installed compiler, AFAIU we now do staged compilation and so the behavior should be much more homogeneous. If you tried and it now works go ahead and submit this :)
