kconfig: add helper to set config symbol from environment variable
Add conf_set_env_sym() that can set an already defined symbol based on the value of an environment variable. Unknown symbols are silently ignored. A warning is printed if the value of the environment variable is unexpected. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>
