[PATCH] kbuild: scripts/kconfig/Makefile cleanup and fixes

[Peter Foley <pefoley2@verizon.net>]

This patch:
Changes the update-po-config target to work when make is run from KBUILD_OUTDIR.
Adds a check to only build kxgettext when needed.
Changes the qconf and gconf targets to change hostprogs-y when they are being built
	like nconfig and menuconfig instead of defining *-objs.
Cleans up the clean-files definitions.
