OpenWrt编译报错

在64bit的Ubuntu上编译，发现有以下报错：

Traceback (most recent call last):
  File "/home/ubuntu/common/build/ipq/scripts/gen_bootconfig_bin.py", line 123, in <module>
    main()
  File "/home/ubuntu/common/build/ipq/scripts/gen_bootconfig_bin.py", line 118, in main
    if process_bootconfig(config_file) < 0:
  File "/home/ubuntu/common/build/ipq/scripts/gen_bootconfig_bin.py", line 90, in process_bootconfig
    ], cwd=outputdir)
  File "/usr/lib/python2.7/subprocess.py", line 710, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1327, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

这是因为qsdk打包时有调用一些32位的可执行文件，64bit系统需要安装一个32位兼容库，解决流程如下：

1. 查看是否开启多架构支持

dpkg --print-foreign-architectures 

2. 安装32位库

sudo apt-get install libc6:i386 libstdc++6:i386

完成上述流程后，建议同步更新一些依赖，例如gcc等。
