It seems nice to be able to add/remove DNS SRV support to telnet
just by installing/removing a binary library (libruli3), instead of
requiring recompilation from the source package. And there is
a greater chance of one system having libdl than libruli, by
default. If libruli is not present, the build-time linking would
irreversibly remove SRV support from the resulting binary.
Besides, dlsym/dlopen portion of the patch is really small.
