I looks like OMPI_MCA_mpi_abort_print_stack=1 is broken. I'm seeing
following warning with it.
--------------------------
$mpirun -np 2 -x OMPI_MCA_mpi_abort_print_stack=1 ./hello_c
--------------------------------------------------------------------------
WARNING: A user-supplied value attempted to override the default-only MCA
variable named "mpi_abort_print_stack".
The user-supplied value was ignored.

It seems HAVE_BACKTRACE is not defined by any configuration but, below
relevant code is guarded with it.
