I get that windows doesn't seem to support symbol level versioning, but I'm not
sure its reasonable to say that its not needed, unless we never have any
intention of building dpdk on windows using a DSO model.  The below definately
solves the immediate problem, but if we plan to support windows with dynamic
library builds, this just kicks the can down the road.

Do we know if we have future plans of supporting dlls on windows in the future?
