Ubuntu18.04编译S3的Linux SDK(Zeta)

按照S3官方Wiki（http://www.sochip.com.cn/s3）的陈述，推荐使用Ubuntu16.04作为Host端系统，笔者是一名乐于并热衷于尝鲜的搬砖工，于是，尝试在最新的18.04上进行编译和构建S3平台的Linux开发包。以下是操作的完整过程，并不顺利，但以成功告终。

安装Ubuntu18.04操作系统 ，安装下面的软件包：

sudo apt-get install git-core gnupg flex bison gperf build-essential \
 zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \
 libgl1-mesa-dev libxml2-utils xsltproc unzip u-boot-tools gawk samba

编译buildroot过程中，会出现若干来自于buildroot packages与Ubuntu18.04自带的工具/包冲突的错误，以下buildroot补丁可处理掉这些错误。

完成上述修改以后，按照S3 Linux SDK的编译方法进行编译即可。
