Sorry I meant new config option. It should be enough to use CFG_OBJ_FILE
everywhere and not create another config option which is just used the
same way.

Is checkpatch ok with this? I think that it should error out that you
shouldn't put externs to .c files.

Definitely. As I told you I am ok with current approach and these things
