Or else we can take the attitude that the mempools and the rings are just a core
part of DPDK and move them and the EAL into a dpdk_core library at link time.
Having the code separate in the git tree is good, but I'm not sure having
the resulting object files being in separate .a/.so files is particularly useful.
I can't see someone wanting to use one without the other.
