Hi Mashiro,
commit 2b50f7ab63685cd247e32ad321f7338ed130d3d5
Author: Masahiro Yamada <yamada.masahiro@socionext.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
David

I think the following will work.
(code was taken from scripts/mkmakefile)
------------------(GNUmakefile BEGIN)-------------------
CROSS_COMPILE := x86_64-linux-gnu-
ARCH := x86_64
MFLAGS += CROSS_COMPILE=$(CROSS_COMPILE) ARCH=$(ARCH)
export CROSS_COMPILE
export ARCH
ifeq ("$(origin V)", "command line")
VERBOSE := $(V)
endif
ifneq ($(VERBOSE),1)
Q := @
endif
MAKEFLAGS += --no-print-directory
.PHONY: __sub-make $(MAKECMDGOALS)
__sub-make:
$(Q)$(MAKE) -f Makefile $(MAKECMDGOALS)
$(filter-out __sub-make, $(MAKECMDGOALS)): __sub-make
@:
------------------(GNUmakefile END)-------------------
Having said that, the previous cheesy workaround sucks.
How about this patch?

I hope you will be able to wrap the top Makefile again.
