last time i did this i wanted to build a stripped down kernel
with as little code as possible.  MULTIPROCESSOR enables a lot
of additional code and data, and if i'm building a stripped down
kernel for a system with only one CPU, that's bloat i don't need.

i didn't bother commiting the changes i made, it was only a
relatively small change (5 files, 10 lines?)
