Error: “Invalid configuration `aarch64-linux-gnu': machine `aarch64' not recognized”的解决办法

背景：64位工具链 交叉编译dbus库时遇到错误“checking host system type... Invalid configuration `aarch64-linux-gnu': machine `aarch64' not recognized”；

解决办法：下载新的config.sub和config.guess，替换掉旧的；

wget -O config.guess 'http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD'
wget -O config.sub 'http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD'
