After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

powerpc-linux-gcc: error: unrecognized command line option '-m'
scripts/Makefile.build:290: recipe for target
'arch/powerpc/purgatory/printf.o' failed

and a few more like that.

OK, this is (most likely) caused by the CONFIG_WORD_SIZE -> BITS change
interacting with the KEXEC_FILE changes. Tomorrow I will do a better
merge conflict resolution patch that fixes all those.

Ah yep looks like that's the problem, patch below should fix it?

I think I'd actually prefer it if purgatory didn't redefine the CFLAGS
from scratch, so I'll see if Thiago can do that and send a new version.

I could move the purgatory inside arch/powerpc/boot and use its BOOTCFLAGS. 
The needs of the purgatory and the boot wrapper are very similar. Would that 
be better?
