Unrolled build for rust-lang#128696

Rollup merge of rust-lang#128696 - Oneirical:second-linkage-rampage, r=jieyouxu

Migrate `staticlib-dylib-linkage` `run-make` test to rmake

Part of rust-lang#121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).

I'm quite sure this has the same issue as the one brought up in [this discussion](rust-lang#128407 (comment)), so I elected to keep the ignore MSVC.
