Rollup merge of #125215 - Oneirical:easy-test-the-second, r=jieyouxu

Browse Source 
Migrate `run-make/issue64319` to `rmake` and rename

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

~~I noticed that the Makefile was not listed in `allowed-run-makefiles` in Tidy. Does this mean the test was being ignored?~~ EDIT: No, it was there, just not in its expected alphabetical order.

EDIT2: Perhaps it could be interesting to clean this test visually by looping over the `rustc` calls, like in #125227.
