Uncompressed kernel doesn't build on x86_64

Hi Christian,

Your recent patch enables uncompressed kernels, but selecting that
option (CONFIG_KERNEL_UNCOMPRESSED) fails on x86_86:

init/Kconfig: add option to disable kernel compression

That's how it fails:

LD init/built-in.o
KSYM .tmp_kallsyms1.o
KSYM .tmp_kallsyms2.o
LD vmlinux
SORTEX vmlinux
SYSMAP System.map
VOFFSET arch/x86/boot/voffset.h
make[4]: *** No rule to make target
`arch/x86/boot/compressed/vmlinux.bin.', needed by
`arch/x86/boot/compressed/piggy.S'. Stop. make[3]: ***
[arch/x86/boot/compressed/vmlinux] Error 2 make[2]: *** [bzImage]
Error 2 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2

arch/x86/boot/compressed/Makefile has no provision for uncompressed
files. There is no definition for suffix-$(CONFIG_KERNEL_UNCOMPRESSED)
so $(suffix-y) evaluates to an empty string and there is no rule to
make vmlinuz.bin.$(suffix-y)

I think the patch should be either reverted or fixed as soon as
possible.

Any suggestions for uncompressed suffix? I'd go with "copy". Then the
"compression" could be a symlink. Alternatively, the "." could be
included in other suffixes, the uncompressed suffix would be empty and
the compression would be an empty statement.
