The script was never intended to be run manually. Its interface is rather inconvenient for this. If you need to run a single test, it's easier to do using llvm-lit (`path/to/lit test/file.cpp`). But if you for some reason want to run the script directly, it should be possible to just modify PATH or switch to the bin directory of the build. I don't think this flag is needed.
