I still believe you can have programs of different types here, and be able to load them. I tried it and managed to have it working fine. If no type is provided from command line we can retrieve types for each program from its section name. If a type is provided on the command line, we can do the same, but I am not sure we should do it, or impose that type for all programs instead.
attr->prog_type is one per object, though. How do we set that one?
