Rollup merge of rust-lang#103931 - pnkfelix:note-eh-personality-limit-atop-lld, r=Mark-Simulacrum

Add note to RELEASES.md regarding issue 102754.

As discussed in [compiler triage meeting today](https://rust-lang.zulipchat.com/#narrow/stream/238009-t-compiler.2Fmeetings/topic/.5Bweekly.5D.202022-11-03/near/307746618); it would have been nice to get this in time for the stable notes, but having it only in nightly only is better than nothing...

   This option may need to be set for distributions that are building Rust with a patched LLVM via `llvm-config`, not the built-in LLVM.
+- Combining three or more languages (e.g. Objective C, C++ and Rust) into one binary may hit linker limitations when using `lld`. For more information, see [issue 102754][102754].
