   5 nommu systems cannot fork() as the hardware cannot support
   6 it. irattach uses it as a minor optimization, but it isnt
   7 necessary for correct functioning of the utility. so add a
   8 NO_FORK define so we nommu peeps can do CFLAGS="... -DNO_FORK=1
   9 ..." and use it in our embedded systems.
