 Various Python API enhancements
 Aarch64/Linux enhancements:

    SVE support.
    Hardware watchpoints improvements for entities stored at unaligned addresses.
        New "c" response to disable the pager for the rest of the current command.
        C expressions can now use _Alignof, and C++ expressions can now use alignof.

GDB 8.1.1 brings the following fixes and enhancements over GDB 8.1:

 * PR gdb/22824 (misleading description of new rbreak Python function in GDB 8.1 NEWS file)
 * PR gdb/22849 (ctrl-c doesn't work in extended-remote)
 * PR gdb/22907 ([Regression] gdbserver doesn't work with filename-only binaries)
 * PR gdb/23028 (inconsistent disassemble of vcvtpd2dq)
 * PR gdb/23053 (Fix -D_GLIBCXX_DEBUG gdb-add-index regression)
 * PR gdb/23127 ([AArch64] GDB cannot be used for debugging software that uses high Virtual Addresses)

 * PR breakpoints/23210 ([8.1/8.2 Regression] Bogus Breakpoint address adjusted from 0xf7fe7dd3 to 0xfffffffff7fe7dd3)

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!

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 592abe9ef53f921554d48085d6482d4507b3e142.

arc-2017.03 is the most recent release toolchain for ARC cores
and it is based on upstream Binutils 2.28 and GCC 6.3.0

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:
