[dpdk-dev] [PATCH v2 6/6] mk: reduce scope of whole-archive static linking

From: Ferruh Yigit <ferruh.yigit at intel.com>

The --whole-archive argument is only required for plugins (drivers)
and libraries used by these plugins.
Currently it covers all libraries.
Reducing the scope of this argument slightly reduce final application size
when statically linked.
