Can I add -latomic to UNSUPPORTED_LLD_FLAGS?

[skhaz]

After adding OpenAL to my project, when compiling to WebAssembly using the Emscripten compiler, I encounter an error during the linking stage. I’m unsure if I should add -latomic to UNSUPPORTED_LLD_FLAGS or if it’s an issue on my end.

My question is: can I open a PR to do this, or is it a different problem?

PS. I read that OpenAL is supported, just like SDL has shims to work on the web.

Other platforms (Windows, Linux & macOS) compile it without issues.

IIUC libatomic is normally provided by glibc? In that case I think adding it to map_to_js_libs in tools/link.py would make the most sense (alongside 'dl', 'm', and 'rt')
