PATCH 1/1 final pre -rc1 kbuild update

Hi Linus.

A few more kbuild goodies:
kbuild: explicit turn off gcc stack-protector
kbuild: introduce utsrelease.h

The stack-protector commit only adds the two -fno-stack-protector and -fno-stack-protector-all flags to CFLAGS in top-level Makefile.

The utsrelease.h commit touches all present users of UTS_RELEASE.

Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild.git

kbuild: explicit turn off gcc stack-protector

Ubuntu has enabled -fstack-protector per default in gcc breaking kernel build. Explicit turn it off for now. Later we may decide to make it configurable if the kernel starts to support it.

kbuild: introduce utsrelease.h

include/linux/version.h contained both actual KERNEL version and UTS_RELEASE that contains a subset from git SHA1 for when kernel was compiled as part of a git repository.
This had the unfortunate side-effect that all files including version.h would be recompiled when some git changes was made due to changes SHA1. Split it out so we keep independent parts in separate files.

Also update checkversion.pl script to no longer check for UTS_RELEASE.

Following is diffstat and shortlog for utsrelease.h commit only.
