When building as shared library, all the drivers are dynamically 
loadable plugins instead of the big pile o' everything you get when 
statically linking. For now, you need to manually load any drivers you 
need with the EAL -d option, eg if you use virtio NIC in the VM you'd 
add this to testpmd: -d librte_pmd_virtio_uio.so

And yes its cumbersome. Doing something about it has been on my todo for 
a while now, just been busy with other stuff.
