Another option is to use a version script. For instance, gnutls11 has

{
   global: gnutls*;
   local: *;
};

which is a bit easier to understand+verify if the library doesn't have a
clean symbol prefix.

Be sure to submit your changes to Upstream. In fact, while you're at it,
using versioned symbols might be a good idea anyway.
