Rollup merge of#125047 - Oneirical:test5, r=jieyouxu
Migrate `run-make/issue-14500` to new `rmake.rs` formatPart of#121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).Note: I find suspicious that `libbar.a` is hardcoded and is not using the `STATICLIB` call to adapt to Windows platforms. Is this intentional? If not, this will need to be changed.
