1.错误描述
新搭建的build server，编译软件时报错：
error: possibly undefined macro: AC_PROG_LIBTOOL
详细的错误信息如下：
[20161201_15:03:11] make[8]: Entering directory `/opt/zyu/CM_develop_d31_clone_zyu/erouter/rg_apps/userspace/public/libs/openssl/crypto/md5'

2.解决办法
检查第一个错误信息：
[20161201_15:03:11] configure.ac:22: error: possibly undefined macro: AC_PROG_LIBTOOL
从错误信息看，是在处理configure.ac文件时出错了，认为AC_PROG_LIBTOOL是未定义的宏，使得执行autoconf失败，安装libtool包得以解决：
sudo apt-get install libtool
