mpich had stopped providing variants of mpi-c.pc etc. so I removed the 
dangling alternatives ...

Can you try to temporarily symlink
   mpi-c.pc -> mpich.pc
   mpi-fort.pc -> mpich.pc

If that makes the build succeed, we can update the alternatives in 
libmpich-dev accordingly.

All the alternatives are managed in libmpich-dev and openmpi-dev, so 
lets keep them there.

But mpi-default-dev should probably have some autopkgtests for "typical 
mpi usage".
