Beside the versioning of symbols, you could also use use one of the
following ld commands (check out the man page for more details):

--exclude-symbols symbol,symbol,...

--dynamic-list=dynamic-list-file

If you are using gcc for linking, then prepend -Wl, to the command, like
-Wl,--exclude-symbols,...

Hope that helps and best regards,
Andi
