kbuild: create .kernelrelease at *config step
To enable 'make kernelrelease' earlier now create .kernelrelease when one of the *config targets are used. Also introduce KERNELVERSION - only user is kconfig. KERNELVERSION was needed to display kernel version in menuconfig - KERNELRELEASE is not valid until configuration has completed. kconfig files modified to use KERNELVERSION. Bug reported by: Rene Rebe <rene@exactcode.de> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
