From f9b017c2c958d968cc5dfd36dc68fc8e5fb89a58 Mon Sep 17 00:00:00 2001
From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
Date: Fri, 11 Jun 2010 09:48:58 +0200
Subject: [PATCH] No AltiVec on SPE
Consider *gnuspe which matches powerpc-unknown-linux-gnuspe where
AltiVec is not available at all. This triplet uses SPE which is
incompatible with AltiVec shares the same opcode range and can't be used
at all.
