gl_GETADDRINFO won't work on Tru64 UNIX 5.1

[Albert Chin]

gl_GETADDRINFO uses the following to test for getaddrinfo:
  AC_SEARCH_LIBS(getaddrinfo, [nsl socket])

This won't work on Tru64 UNIX 5.1. No getaddrinfo() function exists in
libc. Rather, there exists ngetaddrinfo() and ogetaddrinfo():
  $ nm /usr/shlib/libc.so|grep getaddrinfo
  ngetaddrinfo                     | 0004395900636352 | T | 0000000000000008
  ogetaddrinfo                     | 0004395900637184 | T | 0000000000000008

>From <netdb.h>:
  #if defined (_SOCKADDR_LEN) || defined (_XOPEN_SOURCE_EXTENDED)
  #define getaddrinfo ngetaddrinfo
  #else
  #define getaddrinfo ogetaddrinfo
  #endif

The best way to test for getaddrinfo() is to compile a small program
using the function and include <netdb.h>.
