This series allows OVS to consume the DPDK libraries appropriately (static and shared) and simplifies the build. 
When building OVS with DPDK, without this patch, the linker would always pick the shared libraries over static even after specifying the -Bstatic flag. 
With this patch, no such behavior is observed. So, it would be very helpful for the OVS community if this patch is merged in DPDK.

I would also ask this series to be back ported to 19.11 as OVS can immediately consume it on the latest master instead of waiting on the next DPDK release i.e 20.11
