The Apple2 linker configs basically cover two dimension of settings:
1. BIN vs. SYS vs. Loader
2. With Quit code vs. w/o Quit code vs. full LC
Up two now these two dimensions were sort of folded into a number of useful combinations. However with the new asm config and the upcominger overlay config we end up with just to many configs.
Therefore now the second dimension isn't expressed anymore as distinct config. Rather the user has to override __LCADDR__ and __LCSIZE__ in order use the Quite code area or the full LC.
