Changelog:
Assembler:
General:
* Add support for the LoongArch architecture.
* Add an option to control how multibyte characters are handled in
the assembler. Using the option warnings can be generated when
such characters are encountered in symbol names, or anywhere in
the input source file(s).
AArch64 and ARM:
* Add support for more system registers.
* Add support for Scalable Matrix Extension.
* Add support for Cortex-R52+, Cortex-A510, Cortex-A710,
Cortex-X2, Cortex-A710 cores.
* Add support for 'v8.7-a', 'v8.8-a', 'v9-a', 'v9.1-a',
'armv9.2-a' and 'armv9.3-a' architecture extensions.
X86:
* Add a command-line option to encode aligned vector move as
unaligned vector move.
* Add support for Intel AVX512_FP16 instructions.
* The outputs of .ds.x directive and .tfloat directive with hex
input have been reduced from 12 bytes to 10 bytes to match the
output of .tfloat directive.
Linker:
* Add support for the LoongArch architecture.
* Add -z pack-relative-relocs/-z no pack-relative-relocs to x86 ELF
linker to pack relative relocations in the DT_RELR section.
* Add -z indirect-extern-access/-z noindirect-extern-access to x86
ELF linker to control canonical function pointers and copy
relocation.
Other Binary Tools:
* elfedit: Add --output-abiversion option to update ABIVERSION.
* Tools which display symbols or strings (readelf, strings, nm,
objdump) have a new command line option which controls how unicode
characters are handled. By default they are treated as normal for
the tool. Using --unicode=locale will display them according to
the current locale. Using --unicode=hex will display them as hex
byte values, whilst --unicode=escape will display them as escape
sequences. In addition using --unicode=highlight will display
them as unicode escape sequences highlighted in red (if supported
by the output device).
* readelf -r dumps RELR relative relocations now.
* Support for efi-app-aarch64, efi-rtdrv-aarch64 and
efi-bsdrv-aarch64 has been added to objcopy in order to enable
UEFI development using binutils.
* ar: Add --thin for creating thin archives. -T is a deprecated
alias without diagnostics. In many ar implementations -T has a
different meaning, as specified by X/Open System Interface.

The libbfd package definition uses $(ICONV_DEPENDS) and $(INTL_DEPENDS)
but links against neither, leading to libbfd detection failures in other
packages (e.g. bpftools) and on-target relocation problems with libintl.so:
root@OpenWrt:/# ldd /usr/lib/libbfd.so
ldd (0x77db6000)
libc.so => ldd (0x77db6000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x77c6d000)
Error relocating /usr/lib/libbfd.so: libintl_dgettext: symbol not found
Add NLS-conditional linking of "libintl" to fix this. Also remove libbfd
package dependency $(ICONV_DEPENDS) which is not used during building or
linking.

This fixes compilation of gdb on arm64.
The kernel defines "struct sigcontext" in asm/sigcontext.h and musl libc

Kernel 4.14 misses the definitions of struct user_sve_header so we still
have to use the aarch64-sve-linux-sigcontext.h header file which also
provides that and make sure aarch64-sve-linux-sigcontext.h does not
provide the same headers as the kernel or musl.

Seems others are running into this as well.
The problem seems to be that some code may be built
as C++ and not C, which may explain the linker error.
On this thread reply:
https://sourceware.org/ml/gdb/2016-11/msg00045.html
it mentions that the simulator should not call GDB's
"error" function directly, but rather use the "host_callback"
struct.
I have no idea about the use of the GDB simulator within
the OpenWrt/LEDE community.
So, I took the easier route, which is to disable the simulator.
(Also suggested here: https://sourceware.org/ml/gdb/2016-11/msg00047.html )
If needed, I can make an effort to fix the simulator for PPC.

Toolchain built for ARCv1 (read for ARC700 cores) by default has
disabled atomic ops (-mno-atomic). When we build Linux kernel for ARC770
which has LL/SC instructions and thus may handle normally atomic ops we
explicitly add "-matomic" in CFLAGS. But since user-space perf utility has
no way to extract CPU config options from Kconfig/defconfig it uses
compiler default settings.
In case of ARCv2 (read ARC HS38) atomics are enabled by default and so
perf builds perfectly fine thus reenabling perf for ARC HS38 (actually
for non-ARC700 targets).

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:

binutils 2.27 checks if the target compiler supports -Wstack-
usage=262144, and also uses this setting for the host compiler. If the
host compiler is gcc < 4.9 binutils build will fail. This backports 2
commits which are fixing this problem for binutils 2.28.

Support for such old gcc version is not needed.
This reverts commit 2694d43b052a1bf1721ae477dcdbe787f5995d35.
