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:

 [2] https://patchwork.ozlabs.org/patch/726687/

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.

Seems that for PPC, the <linux/ptrace.h> header [from uapi] collides
with musl's <sys/user.h>, for the pt_regs struct.

Seems I tried to upstream this patch a while back:

We have to remove the FPU check, it will run in an endless loop on LEDE

ARC port of GDB is not yet upstream so we need to use
sources from Synopsys GitHub repo.

Given Synopys' commitment to upstream ARC support in GDB
in the nearest future it might be simpler to add a separate
package for ARC GDB instead of patching generic GDB package.
This way once ARC GDB stuff gets uptreamed we'll only need
to remove that new "gdb-arc" package.

Note 1 very minor change in generic gdb package was done -
it now depends on !arc (while "gdb-arc" depends on "arc").
