Subject: net-2.6.24 breaks powerpc mysteriously

With net-2.6.24 (pulled yesterday) applied:

g5:/usr/src/25> ml arch/powerpc/boot/inflate.o
  Using ARCH=powerpc CROSS_COMPILE=

without it applied:

g5:/usr/src/25> ml arch/powerpc/boot/inflate.o
scripts/kconfig/conf -s arch/powerpc/Kconfig
#

.config:308:warning: trying to assign nonexistent symbol INET_LRO
.config:638:warning: trying to assign nonexistent symbol VETH
.config:639:warning: trying to assign nonexistent symbol IP1000

Note that those two COPY commands didn't happen with net-2.6.24 applied, although
that might be because `make' decided they were already performed, dunno.

I also have today's git-kbuild applied here, as well as yesterday's git-powerpc.

But I have enough to fix here so I'm going to do a report-and-run on this one.
I'll release 2.6.23-mm1 in this state for your bug-hunting convenience ;)
