fate no longer passes after installing Fedora21

with
dash ./configure --enable-gpl --cc='ccache gcc' --enable-pthreads --samples=/home/loongson/fate/ --enable-nonfree  --enable-version3 --assert-level=2
i get failure due to illegal instructions

with
dash ./configure --enable-gpl --cc='ccache gcc' --enable-pthreads --samples=/home/loongson/fate/ --enable-nonfree  --enable-version3 --assert-level=2  --cpu=loongson3a --enable-loongson3
it fails in dca tests:
