[RFC] kconfig: Move config targets and lxdialog

[Sam Ravnborg <sam@ravnborg.org>]

Hi Roman.

Played with the idea to shuffle a little around with stuff.
1) lxdialog is solely used for kconfig, so move it below scripts/kconfig
2) Move handling of all config targets to scripts/kconfig/Makefile
	This simplifies top-level makefile,
	and the actual rules is nicer as a side effect.

2) does in no way require 1), but I just combined it here.

I really like moving the config targets away from the top-level makefile.
Allthough I kept them in "make help", so they all still mentioned in
the toplevel Makefile.

Except form moving lxdialog the following files are touched:
 Makefile                 |   39 ++++-----------------------------------
 scripts/Makefile         |    8 ++------
 scripts/kconfig/Makefile |   35 +++++++++++++++++++++++++++++++++--
 scripts/kconfig/mconf.c  |    2 +-
 4 files changed, 40 insertions(+), 44 deletions(-)

	Sam

To try it out:
Execute "mv scripts/lxdialog scripts/kconfig/"
and apply the following patch:
