Subject: Commit seems to prevent use of GNUmakefile wrappers

Hi Mashiro,

	commit 2b50f7ab63685cd247e32ad321f7338ed130d3d5
	Author: Masahiro Yamada <yamada.masahiro@...ionext.com>
	kbuild: add workaround for Debian make-kpkg

seems to prevent the use of GNUmakefile wrappers to set the ARCH and
CROSS_COMPILE make variables.  With this commit, I now see:

	make: Entering directory '/data/fs/linux-fs'
	Makefile:39: Do not include top Makefile of Linux Kernel
	***
	*** Configuration file ".config" not found!
	***
	*** Please run some configurator (e.g. "make oldconfig" or
	*** "make menuconfig" or "make xconfig").
	***
	Makefile:605: include/config/auto.conf: No such file or directory
	make: *** No rule to make target '.config', needed by 'include/config/auto.conf'.  Stop.
	make: Leaving directory '/data/fs/linux-fs'

Do you have a suggestion as to how to work around this?  Here's a sample
GNUmakefile content:

	CROSS_COMPILE	:= x86_64-linux-gnu-
	ARCH		:= x86_64
	MFLAGS		+= CROSS_COMPILE=$(CROSS_COMPILE) ARCH=$(ARCH)
	export CROSS_COMPILE
	export ARCH
	include Makefile
