Currently, tarball builds for powerpc kernels don't have any boot
images (other than vmlinux) present.

Add support for powerpc builds in the buildtar script, to include
a few default images.

RFC: any requests for more/less boot images?

..

+		for img in zImage zImage.pseries zImage.iseries \
+				dtbImage dtbImage.ps3

Yes.  How about all dtbImage, zImage, cuboot, treeboot, etc
that are newer than vmlinux?
