Static libraries can't be linked into shared objects. They can only be 
linked into the final executable. And the final executable doesn't 
need -fPIC -- though we do use -fPIE.

If you add a .o that happens to be in an ar archive into a shared library, 
you've got a convenience library, not a static library. In those cases, 
just link the .o once and for all. There's no need to create the archive.
