Long awaited port for NetBSD/m68k was finally done by Mr. Mutsuki

Nakajima. Since he is not subscribing the mailing list, I'm posting
his patches by his request.  According to him, he has successfully
compiled and passed the regression test on Mac SE/30 running
NetBSD/m68k. Also, another person has reported that with the patches
PostgreSQL is working on NetBSD/sun3 too.
