Check for getopt_long support.

This assume that the standard getopt.h file (from GNU libc) is available as lib/gnugetopt.h. If needed, this file will be linked as getopt.h, but we want to default to the system’s getopt.h file. (See for an explanation about why using the system’s getopt.h file is important.)
