[教程]使用buildroot完全自定义自己的embedded linux系统(nand)

--------------------------------------
apt-get安装了一些软件后，build还是出错。:
Your Buildroot configuration uses pre-built tools for the x86 architecture,
but your build machine uses the x86-64 architecture without the 32 bits compatibility
library.
If you're running a Debian/Ubuntu distribution, install the libc:i386 package.
For other distributions, refer to the documentation on how to install the 32 bits
compatibility libraries.
