Subject: toolchain/arc: update to the most recent release arc-2016.09

arc-2016.09 is the most recent toolchain for ARC cores and
it is based on top of upstream Binutils 2.27 and GCC 6.2.1.

With updated major version of GCC we copied all GCC 6.x patches
for ARC as well as Bintils 2.27 patches.

Note that toochain sports ARCv4 ABI and so must be used
with 4.8+ Linux kernels. Even though it will build v4.4 kernel
perfectly fine on attempt to run user-space apps they won't
work with older kernel. That said previuosly sent RFC patches with
Linux kernel update are required:

 [2] https://patchwork.ozlabs.org/patch/726687/
