    kbuild: improve version string logic

which results in a scripts/setlocalversion call during each build. And
with CONFIG_LOCALVERSION_AUTO, it stores exactly the string you want in
include/config/kernel.release. So we could change kconfig to read that
file instead of building the version string again. To also cover the
!CONFIG_LOCALVERSION_AUTO case, we can add a
include/config/kernel.release.full file to hold the full string each time.

Sorry for jumping in so late in the discussion, I had a bit of backlog
in mail directed to me and linux-kbuild@vger.kernel.org, let alone LKML ;).
