Note that I have requested a binNMU on scalapack (#740620) which should
solve this specific issue. petsc is currently affected by the same
problem as cp2k.

I don't know if we need to think of a better solution to this problem.
As long as mpich does not get renamed again in the foreseeable future,
this may not be necessary.

Cheers,
