I would say it's rather common for vendor/third-party mpi to either
have,

i) Non "standard" mpicc mpiCC, for example 

   mpixlcxx  or  icc -Nmpi 

ii) No wrappers, for example 

  CC foo.cpp -lmpi++ -lmpi

Yes, the configuration tool assumes that no wrapper implies no mpi. It
also assumes that the system has either mpirun, mpiexec or openmpi's
orterun which is often not the case.
