[dpdk-dev] [PATCH 1/2] mk: add LDLIBS variable when producing the .so file

[Nelio Laranjeiro]

Some .so libraries needs to be linked with external libraries.  For that the
LDLIBS variable should be present on the link line when those .so files are
created.  PMD Makefile is responsible for filling the LDLIBS variable with
the link to the external library it needs.
