Qemu testing

Hi!

Based on the sample code provided, I've created an environment which allow *some* testing on a host environment by translating powerpc instruction using qemu. You won't get accurate readings, but at least you'll be able to compile and execute the kernel without access to real powerpc hardware.

In addition, I've copied the 2.6.32 kernel into the tree since I needed to suppress a warning discovered by the more recent gcc-4.8 which caused the kernel compilation to fail.

Perhaps someone else but me will find this stuff useful.
