I get two extra flags for PETSc when I compile with the old
petsc.conf:

  -I/usr/local/lib/petsc
  -I/usr/local/lib/petsc/externalpackages/mpich2-1.0.3/linux-gnu-cxx-real-debug/include

We can just ignore the first one which does not really do anything.

The second gives me exactly the path to the PETSc-configured MPI and
nothing more.

Do you get UMFPACK here? My guess is that you will only get UMFPACK
here if you have told PETSc to download UMFPACK for you.
