Well, in this case I would actually recommend to use the new macros in
the configure for MPI, as in that case a user won't have to set MPICC
manually, but it will be automatically found by the macro.

But as you are not using AX_MPI, this is a non-case. I believe that you
are not using AX_MPI precisely because of the issues with the macro.
