Well, this problem was not seen before as you need to enable hpet support.
Title and commitlog should, at least, mention hpet.

Initial patch preferred eal_thread.h inclusion, but since
rte_thread_setname is defined in rte_lcore.h, I am fine with your patch.
So ack once the commitlog mentions hpet.

Thanks.

Just looking at the first letters of this SHA1 gives a hint ;)
