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:

If the staging dir was deleted, the build needs to recompile some files.
This change speeds up this corner case significantly

graphite is disabled by default and it's not worth carrying ppl and
cloog for supporting this feature on the old gcc 4.8, which is only used
for ARC

-fno-plt and musl-libc patches already get upstream, then dropped
in GCC 6. Other patches are almost identical compared to GCC 5.4.

No extra libc header build step is done, so no extra toolchain is needed
for preparing it.
This saves a significant amount of build time and disk space

This change switches ARC tools to the most recent arc-2016.03
version.
ARC GNU tools of version arc-2016.03 bring some quite significant
changes like:
* Binutils v2.26+ (upstream commit id 202ac19 with additional ARC
* patches)
* GCC v4.8.5
* GDB 7.10

This change adds support of ARC ISAv2 processors in
OpenWRT toolchain.
In general gcc for ARC may compile code for both ISA versions
simultaneously but libgcc will be built only for default
architecture that's why it's necessary to specify --with-cpu
on gcc configuration.
As for uClibc we need to use different configurations for
different ARC ISAs.

This includes binutils, gcc, gdb and uClibc-ng.
Latest release of ARC gcc (as of today it is "arc-2015.06")
is based on upstream gcc 4.8.4.
Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/gcc
Latest release of ARC binutils (as of today it is "arc-2015.06")
is based on upstream binutils 2.23.
Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06
Latest release of ARC GDB (as of today this is "arc-2015.06-gdb")
is based on upstream gdb 7.9.1.
Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06-gdb
Note that for binutils and gdb that come from unified git repository
(which is the case for upstream binutils/gdb today) we need to disable
building of gdb in binutils and binutils in gdb hence in binutils:
------>8------
--disable-sim
--disable-gdb
------>8------
and in gdb:
------>8------
--disable-binutils
--disable-ld
--disable-gas
------>8------
Also in gdb we disable sim because if the following breakage while
building with it:
------------>8------------
/usr/bin/env bash ./../common/genmloop.sh -shell /usr/bin/env bash \
-mono -fast -pbb -switch sem5-switch.c \
-cpu a5f -infile ./mloop5.in \
