I think the error message with and without RTLD_NEXT should be identical.  We
could conceivably add a flag (say RTLD_NOERROR) which prevents setting an error
(dlsym/dlvsym would just return NULL).  Please open a new bug for this.

(If you call dlsym, you really need to have a working malloc at that point.)
