When specifying a triple, we need to provide an architecture. Leaving the triple as `unkown-linux-gnu` or just `linux-gnu` gives us an error along the lines of `flang-new: error: unknown target triple 'unknown-unknown-linux-gnu', please use -triple or -arch`. OTOH, hardcoding an architecture like x86 or aarch64 fails if we're not building that specific backend.

But for general compiler driver level tests, which just print out the command the would have executed (when running with `-###`), it should work without the actual code generation target being available. This is at least how it's done for clang's corresponding tests, most files in `clang/test/Driver` have hardcoded arch triples, without any REQUIRES lines or other exclusions.

Oops, you're right, I was testing with a wrong x86 triple >.< I'll simplify the patch then.
