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.

The correct place for a mpi-c.pc symlink might be mpi-default-dev,
pointing to mpich.pc or ompi-c.pc depending on the default on the
architecture?

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".
