There are three view modes for qconf:

	- Single
	- Split
	- Full

those got broken when gconf was converted to use Qt5, back on Kernel 3.14.
Those patches restore the original behavior.

It requires some environment vars. This would make it a little better:


	export LD=$(which ldd); export CC=$(which gcc); export srctree=$(pwd); scripts/kconfig/gconf Kconfig
	Recursive inclusion detected.
	Inclusion path:
	  current file : arch//Kconfig
	  included from: arch//Kconfig:10

but it seems that something else is also needed.

Thanks,
