6adc05c6e3fdbc8b9f5d915af78ca05d0a09cb17 "some kexec MIPS
improvements" broke pp64 as it turned on -Werror for all archs.

This fixes the warning and hence ppc64 building.

Thanks.

While I'm very much in favour of using -Werror for testing
and these kind of patches are great, I think that -Werror
by default is rather silly. We can't control what will be
a warning in the future and sometimes fixing warnings isn't
appropriate - for instance there are warnings in fs2dt.c at
the moment, that is currently considered an upstream problem.

In short, this patch is great. But I plan to also remove -Werror
as the default now that its been brought to my attention.

Cool.  My second patch should do this for all but MIPS.

Unfortunately the second patch breaks make tarball.
For now I have committed the following:

Subject: [PATCH] build: Don't modify CFLAGS in kexec/arch/mips/Makefile

Revert this portion of recent MIPS changes as it actually effects the
CFLAGS for all architectures.  Moreover I'm somewhat dubious about
defaulting to -Werror for any architecture.
