Rollup merge of #125421 - Oneirical:bundle-them-yet-again, r=jieyouxu

Rewrite `core-no-oom-handling`, `issue-24445` and `issue-38237` `run-make` tests to new `rmake.rs` format

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

The test which is now called `non-pie-thread-local` has an unexplained "only-linux" flag. Could it be worth trying to remove it and changing the CI to test non-Linux platforms on it?
