xu4源码及编译流程
一、环境配置：
1、在linux的根目录下创建名为toolchains的文件夹，用于保存交叉编译软件；
2、拷贝gcc-linaro-arm-linux-gnueabihf-4.7-2013.04-20130415_linux.tar.gz到toolchains文件夹下；
3、 解压
4、tar –xvfgcc-linaro-arm-linux-gnueabihf-4.7-2013.04-20130415_linux.tar.gz
5、配置环境变量，在~目录下，使用vim打开名为.bashrc的文件，添加如下环境变量：
export CROSS_TOOLCHAIN=
/toolchains/gcc-linaro-arm-linux-gnueabihf-4.7-2013.04-20130415_linux/bin/
