I had that exact same problem, ESPECIALLY when pulling in a fresh kernel
tree from kernel.org.

Fixed it by defining the CROSS_COMPILE environment variable or modifying
the Makefile's CROSS_COMPILE to the correct file prefix name, in your
case, it is probaly either

    # export CROSS_COMPILE=ppc_8xx-  (DENK gcc 3.3.3)
or
    # export CROSS_COMPILE=powerpc-linux-  (GNU gcc)

Check your PATH... make sure its picking up the right version...

  # whereis ppc_8xx-gcc

  # ppc_8xx-gcc --version
or
  # powerpc-linux-gcc --version
