* removed some more unused stuff in the simulator makefile

* made the scan for the rockbox source dir a bit cooler, now it can detect
  it even when you create and use a build directory that is on the same level
  as the rockbox dir itself which might make it easier for people that builds
  from (repeatly updated) daily tarballs
* now outputs the found rockbox source code dir found
