The --disable-mpi is a no-op, it defaults to disabled.

Provided MPI libs, headers and runtime are installed in system paths, 
you'd use --enable-mpi:
	./configure --enable-mpi && make -s clean && make -sj8

You'd run it eg. like this (provided all hosts has one CUDA device #0):
	mpirun -host host1,host2 ./john -format=md5crypt-cuda -test

See doc/README.mpi and doc/README-CUDA
