So there are gcc 4.9, 5, 6 versions available for aarch64.  Since the
build robot nowadays uses debian's packaged gcc-6-aarch64-linux-gnu,
it should be better to use gcc-6 in make.coss to better reproduce
reported regressions:

http://releases.linaro.org/components/toolchain/binaries/latest/aarch64-linux-gnu/gcc-linaro-6.2.1-2016.11-x86_64_aarch64-linux-gnu.tar.xz

There are some other files there and I'm not quite sure if that's the
right URL to use. CC aarch64 maintainers for possible inputs.

Thanks,
Fengguang
