# Makefile for the various kconfig 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
# object files used by all kconfig flavours
