Rollup merge of #127935 - tgross35:binary_asm_labels-x86-only, r=estebank,Urgau

Change `binary_asm_labels` to only fire on x86 and x86_64

In <https://github.com/rust-lang/rust/pull/126922>, the `binary_asm_labels` lint was added which flags labels such as `0:` and `1:`. Before that change, LLVM was giving a confusing error on x86/x86_64 because of an incorrect interpretation.

However, targets other than x86 and x86_64 never had the error message and have not been a problem. This means that the lint was causing code that previously worked to start failing (e.g. `compiler_builtins`), rather than only providing a more clear messages where there has always been an error.

Adjust the lint to only fire on x86 and x86_64 assembly to avoid this regression.

Also update the help message.
