The error is different without lld...

The different error without lld is from https://github.com/llvm/llvm-project/commit/e89e8dcfad364d23515de25ac87d26dfe25badbb.
The lld error is older and unrelated, and was unveiled by bug 1799423.

We've updated llvm upstream to be linkable with lld: https://github.com/llvm/llvm-project/commit/61311f3c9363534eda3bc9b8a5edbab80048cdd4
