kconfig (gkc): help about Makefile

Hi Roman,

I'm currently working on the kernel Makefile ($SRC & $SRC/scripts/kconfig)
for adding gkc support but I'm encountering some difficulties...
I have written a standalone Makefile for the gkc package which I'm integrating
into the kernel's Makefile.

I does not understand why it does not run the GTK detection (l75 in the
Makefile). I hope that I am not bothering you but I'm not a guru in this
kind of Makefile: it's too elaborated for me.

# Shared Makefile for the various lkc executables:
# conf: Used for defconfig, oldconfig and related targets
# mconf: Used for the mconfig 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
