When built with --enable-static-nss, gethostbyname2() and functions that call 
it like getaddrinfo() will only do dns lookups and not try /etc/hosts like
gethostbyname() will.

__nss_lookup_function() for gethostbyname2() will try _nss_dns_gethostbyname2_r,
but not _nss_files_gethostbyname2_r.

I'm using an old 2.2.x version, but it appears missing in the code for 2.3.5 as
well.

Below patch will fix the problem:
