I think we should only add this feature when `config.apple_platform == "osx"` ([ref](https://github.com/llvm/llvm-project/blob/afdc5093bb256180b3bec3ff827f21bf23d0f492/compiler-rt/test/lit.common.cfg.py#L411C39-L411C60)). This particular test has `// UNSUPPORTED: ios` so it does not break anything right now, but it's not ideal to have a feature set based on the host OS if we are running on a simulator/device.
