Allow debug kernels for ppc64

[Josh Boyer]

While I'm certainly not advocating for building them normally,
it would be handy to actually be able to build a debug kernel
for ppc64 from time to time.  I had to make the following
changes for this to work (outside of adding ppc64 to the arch
list for debug kernels in kernel.spec).

Anyone have a problem with me committing this?
