自己制作 arm-linux 交叉编译环境 ，看一些教程之类的说 ，先准备好 内核头文件。
执行 make ARCH=arm CROSS_COMPILE=arm-linux- menuconfig
网上说之后应该生成 include/linux/version.h 和 include/linux/autoconf.h
但我没生成，是什么原因？
我 准备编译的 kernel版本是 2.6.34.7 ，环境是 VMware 的 ubuntu10.04
下面是我执行menuconfig命令后的输出：
$ make ARCH=arm CROSS_COMPILE=arm-linux- menuconfig
