On HPUX, shl_load should be called with options BIND_IMMEDIATE rather
than BIND_DEFERRED. That way, if the loaded library has unresolvedreferences, shl_load fails cleanly. As we had it, shl_load wouldsucceed and then the dynlinker would call abort() when we try to callinto the loaded library. abort()ing a backend is uncool.
