Kernel build issues after yesterdays merge by Linus

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
extra optional args, or stop passing them from the ppc64 kernel
install.sh script.
