From e4ca6de1bc5e4ba3f94cf0c501a293c5bc827b10 Mon Sep 17 00:00:00 2001

Subject: powerpc64: Replace some PPC_FEATURE_HAS_VSX with
PPC_FEATURE_ARCH_2_06
We use PPC_FEATURE_HAS_VSX to select a number of POWER7 optimised
functions. These functions don't use any VSX instructions, so
PPC_FEATURE_ARCH_2_06 seems like a better fit.
