Why are we even trying to provide and use 'Samba' shared libraries on
systems without symbol versions?
(And yes, I'm aware that systems without GNU ld can't use them, but
given that Samba libraries such as talloc are meant to be a 'value add'
- not the fundamental purpose of the project, we should be able to set
the rules about where we support them to the places where we can do so
with sanity).
