As recently reported on the Buildroot list: http://lists.busybox.net/pipermail/buildroot/2016-March/155325.html
DNS lookups with Node.js currently fails on uClibc-ng. The reason for this is the way AI_V4MAPPED is handled. According to POSIX, AI_V4MAPPED should be ignored unless ai_family is AF_INET6:
http://pubs.opengroup.org/onlinepubs/9699919799/functions/freeaddrinfo.html
If the AI_V4MAPPED flag is specified along with an ai_family of AF_INET6, then getaddrinfo() shall return IPv4-mapped IPv6 addresses on finding no matching IPv6 addresses (ai_addrlen shall be 16). The AI_V4MAPPED flag shall be ignored unless ai_family equals AF_INET6.
uClibc-ng was also handling AI_V4MAPPED for AF_UNSPEC, fix that.
