no matched libc，please add more libc or try others

打开libcSearcher目录下的libcdatabase:
输入以下命令

rm -rf *
git clone https://github.com/niklasb/libc-database
./get ubuntu 

通过查看libcdatabase下的README.md文件获得get更新指令，执行./get时可能会出现以下报错信息：
Requirements for download or update ‘ubuntu’ are not met. Please, refer to README.md for installation instructions

需要安装astd：

sudo su 
apt-get install zstd
./get  

更新完毕
