This patch adds nbsd_pid_to_exec_file to the NetBSD/amd64 target vector.

OK?

        * Makefile.in (amd64nbsd-nat.o): New dependency.
        * amd64nbsd-nat.c: Include "nbsd-nat.h".
        (_initialize_amd64nbsd_nat): Update target vector to use
        nbsd_pid_to_exec_file.
        * config/i386/nbsd64.mh (NATDEPFILES): Add nbsd-nat.o.
