    tests/compositions: Always fail make check on test error
    
    Appearently sh does not behave consistent on all platforms with
    regards to making the script exit status match the exist status of the
    last command. Use bash instead which seems to be more consistent, and
    also show output to make it clearer when things go wrong.
