I used the 4.6.3 cross compiler for x86_64 from the above location.  It 
seems to be able to build arch/powerpc/kernel/ptrace.c, but then it 
gives a different error:

   CC      arch/powerpc/kernel/epapr_paravirt.o
   AS      arch/powerpc/kernel/epapr_hcalls.o
   CC      arch/powerpc/kernel/prom_init.o
   AS      arch/powerpc/kernel/head_64.o

Please report this bug.
make[2]: *** [arch/powerpc/kernel/head_64.o] Error 1

Yes, that's correct.
