Nothing is broken in the Makefiles. The only thing that was "broken" was the
top-level Makefile futzing directly with $(CROSS_COMPILE) and thus making it
toolchain-biased, so to speak. This has since been deleted.

ISTR your problem was __powerpc__ not being defined. I pointed out that
this was due to a misconfigured compiler, and to which you acknowledged[1].

In any case, if your version of gcc fails this test, then reconfiguring
gcc with --target=powerpc-foo-linux should do the trick[2].

  hubb@mars:~$ powerpc-linux-gcc -dumpversion
  3.3.3
  hubb@mars:~$ echo foo | powerpc-linux-gcc -dM -E - | grep powerpc
  #define __powerpc__ 1
  #define __powerpc 1
  #define powerpc 1
  hubb@mars:~$

Again, none of the Makefiles in the kernel tree are toolchain-specific.
Feel free to point out any specific cases.
