Subject: [PATCH] Fix ppc64 cross-compilation

After the "ppc64 monster cleanup," I get

powerpc-750-linux-gnu-strip: vmlinux: File format not recognized

from my ppc32 strip command when cross-compiling a ppc64 kernel, since
vmlinux is a 64-bit ELF file. This patch fixes my build (and the
resulting kernel boots fine).

Thanks,
Roland
