The idea makes sense to me. Want to hear a second opinion on the API and its naming. |

When building with `rust.rpath = false`, every `rustc` invocation needs to include the library path as well. I particularly ran into this in `generate_target_spec_json_schema` when testing 1.91-beta in Fedora, where we do disable rpath for our system builds. The new helper function will hopefully encourage the right thing going forward.
