找到答案here。要使旧的configure脚本正常工作，您可以更新config.sub文件：
curl 'http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD' > config.sub
这将用最新版本替换config.sub脚本。

包看起来好像很久没有维护了。因此，用于构建配置脚本和辅助文件的autotools可能甚至都不知道x86-64。
假设您安装了autotools - autoconf，automake，libtool等 - 您可以尝试运行autoreconf -ivf，然后再次尝试./configure。您可能会收到很多关于过时宏等的警告，但它可能会有效。
