This seems quite relevant, specific to RELENG_7.  (Said feature isn't
available in earlier releases):

The rtld(1) runtime linker now supports ELF symbol versioning using GNU
semantics. This implementation aims to be compatible with symbol
versioning support as implemented by GNU libc and documented in and LSB 3.0. Also,
dlvsym() function has been added to allow lookups for a specific version
of a given symbol.
