   7 # conf:   Used for defconfig, oldconfig and related targets
   8 # mconf:  Used for the mconfig target.
   9 #         Utilizes the lxdialog package
  10 # qconf:  Used for the xconfig target
  11 #         Based on Qt which needs to be installed to compile it
  12 # object files used by all kconfig flavours
