aix: disable ipv6 link local (#4229)

abmusse · web-flow · commit bfbe4e38d725 · 2023-11-18T19:19:16.000+01:00
AIX does not implement ifaddrs and when retrieving the network interfaces with uv_interface_addresses there was a test failure in tcp_connect6_link_local. For now disable ipv6 link local on aix to: 1) fix broken aix build 2) stop blocking libuv upgrade in node Refs: #4222 (comment) Refs: nodejs/node#50650
