symbols on disk to speed up further loading of the same binaries.
* Various GDB/MI enhancements.
* GDBserver on PowerPC GNU/Linux now supports access to the PPR,
DSCR, TAR, EBB/PMU, and HTM registers.
* Ada task switching support when debugging programs built with
the Ravenscar profile added to aarch64-elf.

*** Changes in GDB 8.2
Support for the following target has been added:
RiscV ELF (riscv*-*-elf)
Support for following targets and native configurations has been removed:
m88k running OpenBSD (m88*-*-openbsd*)
SH-5/SH64 ELF (sh64-*-elf*)
SH-5/SH64 (sh*)
SH-5/SH64 running GNU/Linux (sh*-*-linux*)
SH-5/SH64 running OpenBSD (sh*-*-openbsd*)
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.
Improved flexibility for loading symbol files.
The 'info proc' command nows works on running processes on FreeBSD systems as well as core files created on FreeBSD systems.
A new --enable-codesign=CERT configure option to automatically codesign GDB after build (useful on MacOS X).

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.

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).

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.
