During app build with static library, some libraries wrapped with
--whole-archive compiler flag.

Wrapped libraries are mainly PMD libraries, this is required because PMD
APIs not called directly but run through callbacks registered via
constructor functions.

Also some set of libraries, depends to the PMD libraries needs this,
because of same reason.

All the libraries used by a plugin (any driver) must be in
--whole-archive to ensure that every symbols will be available for the
plugin.

But other libraries can be out of this flag, and this saves some bytes
in final binary.
