There's nothing there that is Windows/Linux specific as far as I know. I assume you can run upstream llvm tests without an issue?

The pattern is used commonly in other tests throughout the llvm tools tests. Given this, I don't think there's enough information in your response to help provide more help. Perhaps try running lit with verbose output, so that you can see that actual paths things expand to. Also, perhaps put a printf or similar in the tool around the site where the error is generated to get it to print the path that is trying to be used. That might help you triage things a bit better.
