使用./build.sh时，编译kernel错误，后来使用./make.sh就没有这些错误了。
另外，编译时要先安装编译相关的库，参照网址

添加参数-Xmx4096m
prebuilts/sdk/tools/jack-admin stop-server
rm ~/.jack-server
- 编译过程中，多次出现jack-server被杀死导致编译错误的情况，
只能重新编译。
我是先把boot kernel 分别编译成功后，又单独编译了android
./make boot 单独编译boot
./make kernel 单独编译kernel
./make android 单独编译android
这三个都编译完成后，再整体编译一遍，主要是打包工作
./make all
最后整个代码编译完成后，差不多140G
编译过程中多次出现空间不足（我在mac mini上装了双系统，分了150G给ubuntu）
各种删东西，最后把代码树里的.git给删掉，才最终编译成功。
坑啊。。
