 So here is a patch to get basic ski console output working.  The ski
 simulator was decoding the wrong registers in ssccnputc() due to
 automagically inlined ssc() which contains a "break" simulated system
 call.
 
 The ski loader "skiload" has almost exactly the same inline assembly
 call for ssc(), but for whatever reason, (maybe ssc() and
 ski_cons_putchar() are in different files?), the ssc() function didn't
 get inlined and I/O worked fine.
 
 If there is a better way to fix, feel free. If I should open another
 PR because this is part of src/ and not pkgsrc/ please let me know.
 
 So with this patch I claim there is enough to say the emulator is
 "working".
 
 Thanks
