python: improved cross-compiling setting ac_cv_buggy_getaddrinfo=no

Note

Only cross-checked the correctness against a native build using glibc!
Other libc implementations like musl need to be checked too!

Failure when running configure
----------------------------------------------------------------------
checking getaddrinfo bug... yes
Fatal: You must get working getaddrinfo() function.
       or you can specify "--disable-ipv6"
