    Reapply D5346 with fix incompatible shell quoting in tests. It seems
    like `$'string'` is not recognized under all test environments, so let's
    avoid it in tests.
    
    Test Plan:
    ```
    hp2ps: "T15904".hp, line 2: integer must follow identifier
    ```
    
    use new ghc and hp2ps to profile a simple program.
