I got an idea.

If in addition to
cmdline_parser (argc, argv, &args_info)
there would also be a
cmdline_parser_allow_unknown_flags(argc, argv, &args_info)

and if there also would be an include directive in gengetopt
configuration files, a program could first let gengetopt parse all the
flags of the program (implemented with includes and
cmdline_parser(argc, argv, &args_info)). After that the program would
run the function cmdline_parser_allow_unknown_flags(argc, argv,
&args_info2) that was generated out of only the common flags.

Advantage: If you have multiple programs that have common flags, you
avoid duplicating code.
Drawbacks: This solution would mean that argv would be parsed twice.
Also group options would be troublesome.
