[PATCH] kconfig: preset config during all*config
Allow to force setting of config variables during all{no,mod,yes,random}config to a specific value. For that conf first checks the KCONFIG_ALLCONFIG environment variable for a file name, otherwise it checks for all{no,mod,yes,random}.config and all.config. The file is a normal config file, which presets the config variables, but they are still subject to normal dependency checks.
