[PATCH 1/2] ppc64: zimage build fix

[Geoff Levand]

Here is an updated version.  I changed the build target names as 
was recommended:

zImage = real mode elf, suitable for pSeries.
zImage.vmode = virtual mode elf, suitable for powermac, and others.

I also fix a problem with 'make clean' leaving stale zImage files.

ppc64-zimage-build-fix.patch:

This patch makes it possible to build ppc64 kernel image files for all
targeted machines when several CONFIG_PPC_XXX machine type options are
enabled simultaneously.  To accomplish this it introduces two new build
targets, zImage.vmode and zImage.initrd.vmode, which will make the proper
image needed by machines with virtual mode Open Firmware.
