After some experimentation, it does not need to be marked: pldebugger gets at that via find_rendezvous_variable(), so there is no need for any explicit linkage at all between plpgsql.so and plugin_debugger.so.
Along the way, I made a quick hack to get pldebugger to load into v15/HEAD. It lacks #ifdef's which'd be needed so that it'd still compile against older branches, but perhaps this'll save someone some time.
Thanks Tom - I've pushed that patch with the relevant #ifdefs added.
