I'm all for testing and more testing but I'm not sure how this particular issue could be tested since this is a build/install system change. In MLIR we have out-of-tree [examples](https://github.com/llvm/llvm-project/tree/main/mlir/examples/standalone) that are actually built in CI to in order exactly to exercise such patches. But lld doesn't right? (Unless I'm blind).
