This looks like a bug in libfakeroot rather than lammps.

The libfakeroot message is a red herring, it's also in precious
successful builds.

lammps built with the rebuilt lammps, the "Invalid communicator" error
message likely indicated that something using openmpi was trying to
communicate with something using mpich.
