My phrasing wasn't quite right, I guess.
The linker will create the PLT stubs by nature of it being an external shared object, or something to that effect.  What I really meant was that it's an error to need a PLT and not have it (linker will warn or error if you try to create a .so and use anything other than PLTREL relocations).
