thor c13d43b0d1 mk/mpi.buildlink3.mk: Add MPI_TYPE=native and diagnostics
This enables use of MPI compiler wrappers present in the host
system via MPI_TYPE=native. Also, it checks for conflicts with
a preintalled different MPI choice from pkgsrc and.

# This Makefile fragment is meant to be included by packages
# that use any MPI implementation instead of one particular one.
# The available MPI implementations are "mpich" and "openmpi",
# or just whatever you have installed in the system (mpi wrapper
# compiler names are standardized).
#
# You have to decide on one implementation and stick to it. Especially
# with the native option, installing an MPI implementation from pkgsrc
# will break things for programs that you built before.
#
# User-settable variables:
#
# MPI_TYPE
# This value represents the type of MPI we wish to use on the system.
# Changing this value is only safe when you ensure that all MPI-using
# packages are re-built, and if switching to native, the MPI package
# from pkgsrc needs to be deinstalled first.
#
# Possible: mpich, openmpi, native
# Default: mpich
