Build openWRT Image

1. sudo tar -Jxv -f xxx-openwrt-sdk-xxx.tar.bz2  
2. apt-get install subversion
   apt-get install wget
   apt-get install libncurses5-dev
   apt-get install zlib1g-dev
   apt-get install gawk
   apt-get install unzip
   apt-get install python
   apt-get install git
   apt-get install file 
3. git init
4. cp util-linux-2.24.1.tar.xz到dl目錄
5. make menuconfig 
6. make V=s (第一次要連網)

P.S.

1. 因util-linux-2.24.1.tar.xz已從server拿掉，自行下載copy到dl目錄。
2. 遇到底下錯誤要先做git init
