You only need to ensure that the class has one non-pure non-inline
function. That's the key function and determines the translation unit
(and by extension the DSO) where the virtual table and the typeinfo is
placed. If there is no such function, both will be defined as weak
mergable symbol and that will not result in a unique address when using
RTLD_LOCAL.
