I dived into the Python API documentation with a fresh mind:

   - gdb.lookup_global_symbol returns Symbol instances;
   - Symbol instances have a symtab attribute;
   - Symtab instances have an objfile attribute.

So it is actually possible to register pretty-printers depending on the 
presence of a symbol! I tried it with my setups and it works properly. :-)

Still to be determined: I don't know if performing a global symbol 
lookup at each objfile load is acceptable from a performance point of view.
