What is the recommended method [by Intel MPI] to specify libmpi_mt.so?

Use that method to specify things to petsc configure.

[i.e you might have to specify the correct compilers, and the correct
compiler options using CC, CFLAGS CPPPFLAGS etc options to configure]

If you are having trouble tell us the recommended way - and what you
get when you try it [i.e configure.log]
