[petsc-dev] p4est w/o MPI

[Isaac, Tobin G]

Matt, this is the configure logic I would like, but I don't know how to do it:
- configure p4est after MPI, but do not require MPI
- if MPI is present, add the '--enable-mpi' flack in formGNUConfigureArgs(), otherwise omit it.

p4est has a mode where it can compile without MPI, I don't know if PETSc is using it, will check.

I don't have MPI (Fugaku w/ gcc) and p4est seems to need it. Is there a work around?
Thanks,
