Bing, the toolchain is downloaded from

https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.6.3/

Just unpack the powerpc package to /usr/local and run this:

/usr/bin/make ARCH=powerpc CROSS_COMPILE=/usr/local/gcc-4.6.3-nolibc/powerpc64-linux/bin/powerpc64-linux- allmodconfig

The gcc version is:

% /usr/local/gcc-4.6.3-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc -v
Using built-in specs.
COLLECT_GCC=/usr/local/gcc-4.6.3-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc
