I looked into the `lld :: MinGW/driver.test` failure on `llvm-clang-aarch64-darwin (doug-worker-4)`.

This isn’t caused by my patch. The builder is hitting an environment issue:
```
Could not create process (.../FileCheck) due to [Errno 24] Too many open files
error: command failed with exit status: 127
```
