Hi Morten,

Not addressing your comments wasn't intentional - just missed your reply prior to sending
v2.

Tracing is tightly tied to eal right now so adding anything "external" there brings in extra
deps. That's why I can't move pmu further down in the lib hierarchy - dpdk won't build if I do.

Once tracing is moved out into its own library, that kind of change should be possible.
