[dpdk-dev] [PATCH v2] mk: add rpath for applications

[Ferruh Yigit]

Add default library output folder to the library search folder.

This is useful for development environment, in production environment
DPDK libraries already should be in know locations.

Patch removes requirement to set LD_LIBRARY_PATH variable when DPDK
compiled as shared library.
