Subject: [PATCH] Added support for SunOS/i386

Merged support for Solaris on i386 by Bill Moore <billm@eng.sun.com>
and cleaned up:

* lib/configure: Recognize SunOS.
* lib/internal.h: Learn how to recognize byte order on SunOS.
* lib/i386-ports.c: Split OS-dependent I/O port access from i386-ports.c.
* lib/i386-io-linux.h: Linux specific part.
* lib/i386-io-hurd.h: GNU/Hurd specific part.
* lib/i386-io-sunos.h: SunOS specific part.
