You seem to have the current working directory in your LD_LIBRARY_PATH environment variable.
问题现象：
在 buildroot make的时候，出现以下的提示：
You seem to have the current working directory in your LD_LIBRARY_PATH environment variable. This doesn't work. make: *** [core-dependencies] 错误 1
解决方法：
暂时将LD_LIBRARY_PATH变量的内容变为空白
LD_LIBRARY_PATH=
成功以后，测试
echo $LD_LIBRARY_PATH
应该是输出了一行空行。
恢复方法：
重新启动终端 或者 重新读取有关的环境变量
source /etc/profile
