a818e29e76 arch: add OpenRISC architecture support
Add support for OpenRISC. See here for more details about
OpenRISC http://openrisc.io.

All buildroot included upstream binutils versions are supported.
Gcc support is not upstream, to be able to enable musl C library
support later, we use the branch with musl support.
At the moment it is possible to build a musl based toolchain,
but bootup in Qemu fails.

Gdb is only working to debug bare-metal code, there is no support
for gdbserver/gdb on Linux, yet.

df4044abfe gcc: disallow 4.8.x for ARMv8 cores
Notice: A53/A57 were in fact supported in aarch64 mode in 4.8 (in aarch32
mode only from 4.9), but it doesn't handle --with-abi, and as there is
unlikely to be any aarch64 based legacy projects unwilling to use a newer
GCC version it is simpler to disallow it for all modes.

16a4241cb7 gcc: backport upstream patch for sync_8 in !glibc
gcc 4.7 introduced the sync_8 builtin functions for ARM. For ARM < v7,
this requires calling into the kernel. However, the failure path of
that call reports an error with the __write() function, which is a
glibc internal function. Therefore, it fails to link with uClibc or
musl. This was fixed in gcc 5.2.0, by replacing the __write() with
a plain write().

For sync_8 itself we have solved this with the conditions on
BR2_TOOLCHAIN_ARM_HAS_SYNC_8. However, the same function is also used
for the implementation of atomics.

For the internal toolchain, we can fix this by backporting the patch
to 4.9.4 and 4.8.5.

d3f0d52144 package/gcc: backport xtensa trap pattern for 5.x
gcc 5.x uses trap pattern extensively to mark locations where program
execution should never get. Default pattern implementation emits a call
to 'abort' function. This function however is not always available, e.g.
it's not available for the libc dynamic linker. Backport implementation
of the trap pattern for xtensa that does not result in a call to
'abort'.

and other failures.

Other important change is that we also update gdb. Now we are
using gdb 7.12.

This version of gdb requires C++ toolchain support so we add
corresponding dependency to gdb Config.in file.

eb6873b1d1 toolchain: Bump ARC tools to arc-2016.09-eng015
As described at:
4520524ba0
this commit continues a series of updates of ARC tools.
This time we're updating tools to arc-2016.09-eng015.

This tag introduces following changes:
1. binutils: Rebase onto upstream master.
2. gcc: Fix devdf3 emulation for arcem, disable TP register when
building for bare metal.

We still keep GDB as it is of arc-2016.03 release because there're some
issues we'd like to resolve before releasing it to wider audience.

So again note this is next engineering builds of arc-2016.09 series
and it might have all kinds of breakages, please don't use it for
production builds.

e6ee58de3e gcc: switch to gcc 5.x as the default
gcc 4.9.4 was the last release of the 4.9.x branch, and the gcc
developes will now only be maintaining gcc 5.x and 6.x:

  https://gcc.gnu.org/ml/gcc-announce/2016/msg00002.html

Therefore, it is time to use gcc 5.x as the default version in
Buildroot. We have been having toolchains in the autobuilders with gcc
5.x for a while, so the vast majority of the problems should have
already been solved.

50332a530b gcc: rename option for ARC gcc
The ARC gcc version is now based on gcc 6.x and no longer gcc 4.8.x,
which makes the option BR2_GCC_VERSION_4_8_ARC a bit irrelevant, as is
the prompt of this option.

This commit therefore renames this option to BR2_GCC_VERSION_ARC, and
adjust its prompt as well.

999c7048c1 toolchain: Bump ARC tools to arc-2016.09-eng013
As described at:
4520524ba0
this commit continues a series of updates of ARC tools.
This time we're updating tools to arc-2016.09-eng013.

This engenering build contains some important GCC updatesthat fixes
some failures for ARC, such as:
http://autobuild.buildroot.net/results/f80/f80ad8a07d9d58b46592c2c99b227197b0f808d3//
http://autobuild.buildroot.net/results/e59/e59e6592fc697cceda359e421387dd905ff04701//
http://autobuild.buildroot.net/results/521/52157aa2b5d75b5338f3bde7ae5beb3d300283d3//

We still keep GDB as it is of arc-2016.03 release because there're some
issues we'd like to resolve before releasing it to wider audience.

So again note this is next engineering builds of arc-2016.09 series
and it might have all kinds of breakages, please don't use it for
production builds.

Disable libcilkrts when building static, as there is no static version:

1bd02bc230 gcc: remove BR2_GCC_ENABLE_TLS option
The current BR2_GCC_ENABLE_TLS can cause users to make incorrect
choices, and is not very useful. This options allows to decide whether
we pass --enable-tls or --disable-tls to gcc, to enable or disable
support for Thread Local Storage.

Its behavior is:

 - The option is default to "y" but only exists if we're using
   uClibc/NPTL or glibc.

 - When we're using uClibc, the option can be disabled.

So, in practice, this means that currently:

 - TLS support is always on for glibc

 - TLS support is on by default for uClibc/NPTL, but can be disabled in
   the configuration. This is in fact bad and causes the build failure
   reported in bug #7424 (this bug is still reproducible on master)

 - TLS support is always disabled for uClibc/no-thread and
   uClibc/linuxthreads.

 - TLS support is always disabled for musl. This does not cause any
   build failure, but musl can use TLS support, and therefore be more
   efficient. According to
   http://www.openwall.com/lists/musl/2012/10/04/1, "Note that if you've
   been building gcc with --disable-tls, __thread was already working
   but gets emulated (very poorly; it's slow and will abort() if it runs
   out of memory) through libgcc.".

So, this commit completely removes the BR2_GCC_ENABLE_TLS and instead
makes the right choice inside gcc.mk directly:

 - TLS support enabled for glibc, musl and uClibc/NPTL

 - TLS support in other cases, i.e uClibc/no-thread and
   uClibc/linuxthreads.

We have intentionally *not* added the option to
Config.in.legacy. Indeed, the new behavior is *exactly* the same as the
older behavior, with the exception of:

 - People can no longer disable TLS support in uClibc/NPTL, which was
   anyway causing a build failure and therefore was not used.

 - TLS support is now enabled on musl, but people using musl already had
   BR2_GCC_ENABLE_TLS not set, so they wouldn't get the legacy warning.

Fixes bug #7424.

This time we're updating tools to arc-2016.09-eng010.

been added to eng010.

We still keep GDB as it is of arc-2016.03 release because there're some
