While the gnu style for symbol versioning is the most usual,
--enable-symvers[=style] can be provided several values,
gnu, gnu-versioned-namespace, darwin, darwin-export, and sun,
depending on users needs.
Introduce the SYMVERS_CONF variable to allow the user to
configure the symbol versioning in shared libraries.

just turn the RHS into variable not full option

I did think about that, and I can do it, but I think I would have to also
create a PACKAGECONFIG and since AFAIC no one is changing the style I'm not
sure it's worth the complication of the code, and this still allows us to
remove the enablement entirely, not just changing the style.
