* If not defined CONFIG_MENUCMD do nothing
* If CONFIG_MENUKEY is 0 and was pressed any key run env "menu_cmd"
* If pressed key was CONFIG_MENUKEY run env "menu_cmd"
* If CONFIG_MENUKEY is not defined run env "menu_cmd" always
* CONFIG_MENUKEY working if defined CONFIG_MENUCMD and CONFIG_BOOTDELAY >= 0
