error: linking with arm-linux-musleabihf-gcc failed: exit status: 1

How do you begin to debug these type of errors? From one directory it builds fine and from another it does not. What I was trying to do was test my GitHub Action Pipeline. On my machine, no sweat. In GH Action - FAIL. Started by doing a custom runner so I could get it to run on a machine I can control. Same results. The clone of the repo compiles fine, the _worker directory source does not. I had a similiar issue once and it was the underlying docker container and file permission. I cant seem to get "underneath" this one though. Error is below:

Are you using atomics in your crates? I'm guessing this is related to code using std::sync::atomic::AtomicInt? Normally these atomics are implemented in terms of these intrinsics (like as hinted here).

Duplicate of #367.

This no longer replicates as of the latest main using the latest vendored OpenSSL. Note that you can't use the repository versions since those are linked to glibc. However, similar targets such as armv5te-unknown-linux-musleabi do fail with nearly identical errors, so if this reproduces later, I'll reopen this.
