locore.s: Made the APM stuff depend on NAPM > 0 rather than a separate
"APM" macro. machdep.c: Made the APM-descriptors unconditional. Bruce: if these still conflict with your debugger, please put in a reservation for your debugger. These three desc. can be anywhere, as long as they are contiguous, so just move them as needed.
