              ^^^^^^^^^^^^^^

  Check the Makefile under KERNELDIR directory.

Sorry, but I didn't find a Makefile under KERNELDIR.
Why is it necessary to check that makefile anyway???

As to the Makefile that I posted before, if I can changed that file to build the
.c into .bc rather then .o, that would also solve my problem!
Thank you!

  Well, `make -C $DIR` means it will change to that directory and start
to make. That's why I sugguest you looking for Makefile under KERNELDIR.
Where do you download the kernel source?
