Log Message:
Try not to rebuild nbmake so often:

* Add a try_set_TOOLDIR function which tries to be clever about setting
  TOOLDIR if possible;
* Call try_set_TOOLDIR from rebuildmake;
* Add nobomb_getmakevar, which works like raw_getmakevar except
  never bombs;
* Reimplement raw_getmakevar in terms of nobomb_getmakevar;
* Add a second arg to find_in_PATH to control the result when the
  program cannot be found.
