我采用了最简单的用于测试的模块程序。Makefile内容如下：

ifneq ($(KERNELRELEASE),)
obj-m := test.o
else
KERNELDIR ?= /usr/src/arm/linux
default:
$(MAKE) $(MAKEARGS) -C $(KERNELDIR) SUBDIRS=$(shell pwd) modules
endif
运行make命令时，出现信息：

make -C /usr/src/arm/linux SUBDIR=/home/scripts/leds/mod modules
make[1]: Entering directory `/usr/src/arm/linux'
CHK include/linux/version.h
make[2]: `arch/arm/kernel/asm-offsets.s' is up to date.
make[2]: `include/asm-arm/mach-types.h' is up to date.
Building modules, stage 2.
MODPOST
make[1]: Leaving directory `/usr/src/arm/linux'

本来还应出现另外三行信息

CC /home/scripts/leds/mod/test.o

CC /home/scripts/leds/mod/test.mod.o
LD [M] /home/scripts/leds/mod/test.ko

但是编译时没有出现，也就是当前目录下的模块文件没有被编译，请问是怎么回事？
