  * Re-adjust interaction between -ddump flags and force-recompilation
  
  If you say -ddump-xx we effectively add -fforce-recomp, so that you
  see your dump output.  But this works badly in --make mode, because
  you get the ddump output for every module, which is probably not what
  you want.  This patch forces recompilation with -ddump-X only in one-shot
  mode.  
  
  Of course, this only affects people using -ddump options.
