@illegalprime this pulls in stuff from your PR #58606. Do you mind if I take over since the last commit to that PR was April of last year?? I'll make sure you're still credited with authorship in the git commits.

@lopsided98 you had an alternate way of fixing this, right? Does it work for armv7l and across gcc versions too? If so maybe we should compare these approaches and pick one to advocate for merging.

I'm currently testing my version on armv7l. I don't know of any reason it wouldn't work on other gcc versions, but I haven't tested yet.

@lopsided98 can you publish it as a branch? I'd love to try it out too.

I successfully built pkgsCross.armv7l-hf-multiplatform.hello with my patch

@lopsided98 how does your branch differ from the changes proposed here? Can you elaborate?

The functional difference is that the libraries are placed in $lib/$targetConfig/lib (which is the directory convention using by the GCC build scripts) rather than $lib/lib. This requires a minor change to cc-wrapper. Subjectively, I believe it is cleaner because it unifies the handling of the cross and non-cross cases and is therefore easier to reason about.

Closing in favor of #81844

Great. Glad this is fixed :)
