这是 config.log 的内容：
我禁用了它，_FORTIFY_SOURCE因为它引发了错误。但我完全不知道可能出了什么问题。
（我知道这个帖子，建议--disable-sanity-checks）
如果我从源文件夹中删除 linuxthreads(2.3)，配置不会失败。
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by GNU C Library configure (see version.h), which was
generated by GNU Autoconf 2.68. Invocation command line was

configure: exit 0
答案1
这是因为 linuxthreads 的配置文件中只有一行exit 0（这显然导致整个脚本在读取时停止）。
我所做的是将linuxthreads的配置内容更改为libidn的配置内容：
libc_add_on_canonical=
libc_add_on_subdirs=.
