[Users] MPI thorn doesn't output error messages

[Erik Schnetter]

I am seeing this error message from thorn MPI:

Running configuration script for thorn MPI:
MPI could not be configured.

CST error 1:
  -> Configuration script for thorn MPI returned exit code 5
     (no error message)

Finished running configuration script for thorn MPI.

That's not good enough, I really need to see either an error message,
or at least a line number. The previous MPI configuration script
echoed all commands to stderr, so that it was easy to see where things
fail.
