if symbols are being redirected to provide the new time64 ABI, dlsym must perform matching redirections; otherwise, it would poke a hole in the magic and return pointers to functions that are not safe to call from a caller using time64 types. rather than duplicating a table of redirections, use the time64 symbols present in libc's symbol table to derive the decision for whether a particular symbol needs to be redirected.
