From b1fc86a42d4ae47c0d66870334f95ecd5c75ccef Mon Sep 17 00:00:00 2001
From: imp <imp@FreeBSD.org>
Date: Fri, 5 Mar 2010 16:56:08 +0000
Subject: Add support for o32 (when it isn't the default), n32, n64, and o64 to
 the linker spec.  Provide the ability to have a default ABI that's different
 than o32 (again, for all 4).

Submitted by:	C. Jayachandran (JC) with tweaks for o64/o32 by me
