It looks like the compiler just cannot compile the kernel code.
-maccumulate-outgoing-args is only used on the x86 architecture, so I
assume the build system is picking up x86 makefiles while using a
PowerPC compiler.

I think ARCH should be specified on the make command line in addition to
other arguments:

make ARCH=powerpc
