getopt.c and getopt1.c elide the code if compiling with GNU libc.  
Traditionally this would have been enough, but the existence of other
libcs which also implement the getopt_long interface means such configure
checks might make sense, unless the argument is that the GNU version
should always be used in preference to a non-GNU version in another libc.
