John Mcnamara and I were discussing enhacing the validate_abi script to build
the dpdk tree faster with multiple jobs. Theres no reason not to do it, so this
implements that requirement. It uses a MAKE_JOBS variable that can be set by
the user to limit the job count. By default the job count is set to the number
of online cpus.
