--- Comment #5 from Michael Meissner <meissner at gcc dot gnu.org> --- Ok, after figuring out that I was building on gcc2-power8.osuosl.org (the old big endian system that is going away), I checked out the current revision (221024) and rebuilt a tool chain on gcc2-2-power8.osuosl.org. I now see the error if I build without the --with-cpu=power8 option (the options I used were --prefix=<xxx> and --disable-multilib).
