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

As of version 4.21, strace enforces mpers by default. The current
implementation of aarch64 compat in strace assumes it's identical to
ARMv7 EABI and therefore tries to enable m32 personality support. As
there is no -m32 support on aarch64, this causes the build to fail.
Restore previous strace behavior to fix build on aarch64.

Allow building perf on uncommon targets again.

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.

The kernel needs to have PERF_EVENTS built otherwise we will run into

89 (Function not implemented)
perf_event_open(..., 0) failed unexpectedly with error 89 (Function not

Error:
The sys_perf_event_open() syscall returned with 89 (Function not

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.
