AFAIK, normal (non "whole") static libs mean that the shared library
(or executable) generated from this library will have all
unused/unreferenced code removed. That is obviously a problem for a
library that is a dependency of something else - the GCC's linker will
throw away all "unused" code, because it has no idea it will be needed
in the future.

The LOCAL_WHOLE_STATIC_LIBRARIES turns this optimization off and
includes all code verbatim in the generated shared library/exe.

I believe it triggers the "--whole-archive" switch of the GNU linker.
