x86_64编译JPEG遇到Invalid configuration `x86

      把 /usr/share/libtool/config/config.guess 覆盖到相关软件自带的config.guess   
      

      把 /usr/share/libtool/config/config.sub 覆盖到相关软件自带的config.sub   
      

      ./configure --enable-shared --enable-static
      

      但是会遇到没有安装libtool
      

      yum install -y libtool
      

      cp /usr/share/libtool/config/config.guess 
      

      cp /usr/share/libtool/config/config.sub
