  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.

Changelog: add missing EXTRA_LDFLAGS variable necessary to link with an
external library when it is not installed on the system or located somewhere
else.
