Talk about punting and not going to any trouble to DTRT:

contrib/binutils/include/getopt.h
/* Many other libraries have conflicting prototypes for getopt, with

	   differences in the consts, in stdlib.h.  To avoid compilation
	   errors, only prototype getopt for the GNU C library.  */

so manually define HAVE_DECL_GETOPT since configure doesn't offer any way
to set it... and its unistd.h not stdlib.h dang it.
