-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 \

Make musl provide libssp_nonshared.a and make GCC link it unconditionally
if musl is used. This should be a no-op if SSP is disabled and seems to be
the only reliable way of dealing with SSP over all packages due to the mess
that is linkerflags handling in packages.

Several versions of gcc have an issue in libstdc++v3 where the build may
clobber stamp-bits with a link to itself. This doesn't manifest itself
on all systems. On several Ubuntu systems, this doesn't appear to be a
problem, but it is an issue on Fedora 16 systems.
To fix the issue, we'll simply filter out stamp-bits from the symlinks
to be generated.
Note: gcc 4.4.7 is unaffected by this issue, so no fix is necessary
there.

These instructions are for 64-bit load/store. On ARMv5TE, the CPU
requires addresses to be aligned to 64-bit. When misaligned, behavior is
undefined (effectively either loads the same word twice on LDRD, or
corrupts surrounding memory on STRD).
On ARMv6 and newer, unaligned access is safe.
Removing these instructions for ARMv5TE is necessary, because GCC
ignores alignment information in pointers and does unsafe optimizations
that have shown up as bugs in various places.

The .init and .fini sections are built by concatenating code
fragments. Putting mips16 code in the middle of a mips32 code block
doesn't work. Make gcc built the magic crt stuff in no-mips16 mode.
This is specific to 4.6-linaro but is probably portable to other gcc
flavors. Adding this to the t-libgcc-mips16 makefile fragment is a
hack not suitable for pushing upstream, but there is no mips/t-linux
or mips/t-uclibc and I am not going to touch gcc/configure for two
lines.
