  Instead of using getopt_long return value, strcmp was used to
compare the input parameters with the struct option array. This
patch get rid of all those strcmp by directly binding each longopt
with an int enum.

Bugzilla ID: 238
Fixes: de3cfa2c98 ("sched: initial import")
Fixes: cb056611a8 ("eal: rename lcore master and slave")
