Right, you have a 64 bit only compiler. Also it is version 4.1.0 which we now black ban (I think).  You need to either build a biarch cross compiler (--enable-targets=all) or try:

$ cat >xxx <<EOF
CONFIG_PPC64=y
EOF
$ KCONFIG_ALLCONFIG=xxx make allnoconfig
$ make vmlinux

let us know if that works :-)
