Kernel build issues after yesterdays merge by Linus

This is under Ubuntu Utopic Unicorn on a Power 8 system while simply
trying to build with the Ubuntu standard kernel config. It could be that
these issues come about because we do not have an rc1 yet but I wanted to
give some early notice. Also this is a new arch to me so I may not be
aware of how things work.

Can you try my current -next ? It has an additional fix or two by Anton
for building with ABIv2 that I'll send to Linus tomorrow.

Cheers,

Hi Christoph,

The TOC symbol export is special and I think we might need to get our
script to ignore it.

Shows how much we use make install :) Below is a quick hack to get you going
but we should look at either fixing the Ubuntu installkernel to handle

It seems like passign the zImage files is probably wrong.  How about:

Looks reasonable to me. Grant added this back in commit 29f1aff2 (powerpc:
Copy bootable images in the default install script) but the other archs have
gone in a different direction and created make zinstall targets.
