oldnoconfig is an alias of olddefconfig, because people already are dependent

on its behavior(sets new symbols to their default value but not 'n') with the

counter-intuitive name.

lxdialog stuff

check-lxdialog := $(srctree)/$(src)/lxdialog/check-lxdialog.sh

Use recursively expanded variables so we do not call gcc unless

we really need to do so. (Do not call gcc as part of make mrproper)

===========================================================================

Shared Makefile for the various kconfig executables:

conf: Used for defconfig, oldconfig and related targets

nconf: Used for the nconfig target.

Utilizes ncurses

mconf: Used for the menuconfig target

Utilizes the lxdialog package

qconf: Used for the xconfig target

Based on QT which needs to be installed to compile it

gconf: Used for the gconfig target

Based on GTK which needs to be installed to compile it

object files used by all kconfig flavours
