    This patch resulted from the discussion in D2431 and should be merged

    @erikd and @trommler reported errors like
    
    ```

    on PowerPC. @simonmar suggests to add the specific exports to
    `rts/package.conf.in`. This patch does exactly that, including all
    other atomic ops as they probably (maybe someone can verify?) suffer
    from the same problem on PPC.
    
    Test Plan: Please make sure to build on PPC.
