我编写一个Hello world的驱动模块，和独立Makefile文件。
Makefile文件内容如下：
module_name = hello_world
ifneq ($(KERNELRELEASE),)
obj-m := $(module_name).o
else
KERNELDIR ?= /opt/FriendlyARM/mini2440/linux-2.6.32.2
PWD := $(shell pwd)
module:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules
clean:
@-rm -rf *.o *.mod.o $(module_name).ko *.mod.c
.PHONY: module clean
endif
运行make module编译arm二进制驱动模块时，出现如下错误提示：
make -C /opt/FriendlyARM/mini2440/linux-2.6.32.2 M=/root/Module_test modules
make[1]: Entering directory `/opt/FriendlyARM/mini2440/linux-2.6.32.2'

开发环境为fedora9（2.6.25-14.fc9.i686），请问出现该编译问题的原因是什么？为什么在mini2440提供的linux-2.6.32.2内核源码中编译就没问题？我应如何调整独立Makefile？
