Research direction

Start in configure.ac around line 5212, where the getaddrinfo bug check is configured, and inspect how EAI_NONAME is handled in a networkless environment. Reproduce the configure failure on FreeBSD 13.1 without network access; done means the check behaves correctly for that environment without requiring a working network connection.

Bug report

When python is built in networkless environment (the way system packages are (or should be) built in many distros), test for getaddrinfo bug fails:

checking getaddrinfo bug... yes
configure: error: You must get working getaddrinfo() function or pass the "--disable-ipv6" option to configure.

what happens here is getaddrinfo

https://github.com/python/cpython/blob/8790d4d31fcd3abaccf31d27f72a8684adfc9dee/configure.ac#L5212

returns EAI_NONAME
