GDB 8.1 includes the following changes and enhancements:
* Breakpoints on C++ functions are now set on all scopes by default
("wild" matching);
* Support for inserting breakpoints on functions marked with C++ ABI tags;
* Target floating-point arithmetic emulation during expression evaluation
(requires MPFR 3.1 or later);
* Various Python Scripting enhancements;
* Improved Rust support; in particular, Trait objects can now be inspected
when debugging Rust code;
* GDB no longer makes assumptions about the type of symbols without
debugging information to avoid producing erroneous and often confusing
results;
* The 'enable' and 'disable' commands now accept a range of breakpoint
locations;
* New 'starti' command to start the program at the first instruction;
* New 'rbreak' command to insert a number of breakpoints via a regular
expression pattern (requires Python);
* The 'ptype' command now supports printing the offset and size of
the fields in a struct;
* The 'gcore' command now supports dumping all the memory mappings
('-a' command-line option);
* New shortcuts for TUI Single-Key mode: 'i' for stepi, and 'o' for nexti;
* GDBserver enhancements:
** Support for transmitting environment variables to GDBserver;
** Support for starting inferior processes with a specified initial
working directory;
** On Unix systems, support for globbing expansion and variable
substitution of inferior command-line arguments;
* Various completion enhancements;
* The command used to compile and inject code with the 'compile' command
is now configurable;
* New '--readnever' command-line option to speed the GDB startup when
debugging information is not needed;
* Support for the following new native configurations:
** FreeBSD/aarch64 (aarch64*-*-freebsd*);
** FreeBSD/arm (arm*-*-freebsd*);
* Support for the following new targets:
** FreeBSD/aarch64 (aarch64*-*-freebsd*);
** FreeBSD/arm (arm*-*-freebsd*);
** OpenRISC ELF (or1k*-*-elf)
* Removed support for the following targets and native configurations:
** Solaris2/x86 (i?86-*-solaris2.[0-9]);
** Solaris2/sparc (sparc*-*-solaris2.[0-9]);

The GDB Text User Interface (TUI) is a terminal interface
which uses the curses library to show the source file,
the assembly output, the program registers and GDB
commands in separate text windows.
In other words it's a friendlier interface for idiots like me!

This commit finally bumps ARC tools to the most recent arc-2017.09 release version.
ARC GNU tools of version arc-2017.09 bring some quite significant changes like:
* Binutils v2.29 with additional ARC patches
* GCC 7.1.1 with additional ARC patches

Since version 8.0, gdb requires at least gcc 4.8. Unfortunately some of
the buildbot slaves don't meet this requirement, and fail to build LEDE
after the gdb upgrade. Revert to the previous gdb version for now.
This reverts commit 592abe9ef5.

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:

Use ./patches and ./patches-arc instead of version dependent patches.
We should have only one main supported version (along with the special
case for arc).

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

With bump of upstream GDB from 7.9 to 7.10 at least
100-no_extern_inline.patch became incompatible with
ARC gdb (which is still based on upstream 7.9 branch).
So until ARC support is not completely upstreamed
(which we expect to happen in coming months) we'll need to have
separate patches for ARC gdb.
This time clean build-tested for Netgear WNDRMAC & AXS101.

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 \
