发现kernel使用android的prebuilt/linux-x86/toolchain/arm-eabi-4.4.0下的arm-eabi-gcc不能编译通过，该现象在去年8月15号就已经存在，今天很多人都出现了该问题！

锁定到Thu Jan 21 14:24:36 2010 -0800日期之后的toolchain开始就不能编译我们的kernel,具体信息如下：

在该4b06260a916be762d0dd1b93e97306f1b90e3889 哈希之前的toolchain-->arm-eabi-gcc可以正常编译,从Mon Jan 25 09:53:00 2010 -0800的406fda666bb7c8dd4de3294c3827a27c8fd4119c版本开始就不能正常使用arm-eabi-gcc编译kernel了,大家可以尝试一下:
尝试步骤如下：

1. 进入kernel执行如下命令
git clean -xdf
2. 导出arm-eabi-工具链所处系统路径
export PATH=/home/luther.gliethttp/froyo/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin:$PATH
3. 编译
make -j4或make -j4 V=1
