commit: 0e9f9fd20ce931cc2cf0519c56ae33fc74d656ad openrisc: add atomic bitops
date: 8 days ago
config: openrisc-or1ksim_defconfig (attached as .config)
compiler: or32-linux-gcc (GCC) 4.5.1-or32-1.0rc1

Hello,

This should not happen, I patched make.cross to download the
or1k-linux-gcc toolchain.

Could you let me know if there is really something wrong? Maybe an old
version or make.cross on this host?

Ah sorry I forgot to change the robot code accordingly, which relies
on pre-downloaded cross binaries. Will do so right away.

Thanks,
Fengguang

reproduce:
wget https://raw.githubusercontent.com/01org/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout 0e9f9fd20ce931cc2cf0519c56ae33fc74d656ad
# save the attached .config to linux build tree
make.cross ARCH=openrisc
