We should also run the lint for other stable (non-rustc-specific) ABIs such as win64, sysv, aapcs, interrupt ABIs, etc.

Do you have an example that doesn't check? In #64641 I specifically excluded Rust ABIs from the check, because before it was checking all extern blocks regardless of chosen ABI. Maybe there's another path that's checking differently.

Hm, it might very well have been a code path that was only introduced in #65134 (I turned a review comment there into this issue). So I'll close this now.
