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.

As described at:

this commit continues a series of updates of ARC tools.
This time we're updating tools to arc-2016.09-rc1.

This update contains a lot of important fixes, e.g. it fixes:
http://autobuild.buildroot.net/results/4c7/4c77f33c842b37bf28cb931edf1b290e1bf4d93c//
http://autobuild.buildroot.net/results/902/902729a0b98675ad803939e3ecdcf230065a6012//
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.

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.

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.

62504125f8 gcc: fix gcc version dependencies for the PowerPC64/musl exclusion
In commit
5ab751ca44 ("toolchain-buildroot: allow to
build ppc64(le) musl toolchains"), support for building a musl toolchain
for ppc64(le) was added. Since this support only works with gcc 6, some
additional dependencies have been added to the older gcc versions so
that they cannot be selected on ppc64(le)/musl.

Unfortunately, the expression of the dependency was wrong, and leads to
those older gcc versions being non-selectable if you're not using
musl. Indeed, the dependencies look like this:

  depends on !BR2_powerpc64 && !BR2_powerpc64le && BR2_TOOLCHAIN_USES_MUSL

So as soon as you're not using musl, BR2_TOOLCHAIN_USES_MUSL is false,
so the entire condition is false, and the gcc version is not available.

Due to this, only gcc 6.x can be selected currently with uclibc or
glibc, which is clearly not the intended behavior.

This commit reworks those dependencies to:

  depends on !(BR2_TOOLCHAIN_USES_MUSL && (BR2_powerpc64 || BR2_powerpc64el))

which more clearly expresses what we want:

 "We don't want to (have a toolchain that uses musl and (be building
  either for PPC64 or PPC64le))"

0d8a05c38e bfin: fix issues with internal toolchain, re-enable C++ support
The three patches allow to compile applications using TLS emulation from
libgcc or C++ applications.

The patches 892-libgcc-mkmap-symver-support-skip_underscore.patch and
893-libgcc-config-bfin-use-the-generic-linker-version-in.patch fixes how
libgcc is generated, by making the necessary libgcc symbols declared
"GLOBAL", and therefore visible outside of libgcc. This fixes a large
number of undefined reference issues (for either C++ applications or
applications using TLS emulation). This was reported as gcc PR74748.

The patch 894-libgcc-fix-DWARF-compilation-with-FDPIC-targets.patch
allows to build DWARF in FDPIC mode. This patch replaces the older
892-disable-dwarf-bfin.patch, as instead of disabling DWARF support, it
fixes it. This was reported as gcc PR68468.

In order to get C++ working without unresolved symbols, we also need to
disable symbol versioning (--disable-symvers). This is a remaining issue
in gcc which will be investigated at a later point.

Since this commit fixes C++ support in Blackfin, it re-enables the
selection of C++ support for this architecture.

5ab751ca44 toolchain-buildroot: allow to build ppc64(le) musl toolchains
Latest musl release supports ppc64 architecture (both big endian and
little endian), so this commit adds support for this.

Since musl implements the ELFv2 ABI for both big-endian and
little-endian PowerPC64, we have to force using this ABI on PowerPC64
big endian (normally elfv1 is the default).

Also, only gcc 6.x has the necessary changes to support musl on PowerPC
64, so we restrict the gcc version selection accordingly.

Tested with Qemu for big endian and little endian configurations.

f0e1381ef9 toolchain: Bump ARC tools to arc-2016.09-eng008
As described at:
4520524ba0
this commit continues a series of updates of ARC tools.
This time we're updating tools to arc-2016.09-eng008.

Main updates were made for gcc. It was switched to GCC 6 and to
OSABI v4.

Besides this patch fixes buildroot ARC failures connected to
"crtbeginT.o" object file missing. This issue lead to two main errors:

1) "crtbeginT.o: No such file or directory", e. g. bootutils-1.0.0.
No comments are required here I hope.

2) Errors like "compiler cannot create executables", e.g.:
  a) host-gcc-final-arc-2016.09-eng007 static build,
  b) aespipe-2.4c.
That was caused because the test to determine if compiler is able to
create executables was failing due to missing "crtbeginT.o" file.

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.

9ca80d92e0 gcc: disable C++ support for Blackfin
As discussed with Waldemar, the C++ support for Blackfin is currently
broken, and we don't have a fix in sight for the 2016.08
release. Therefore, this commit disables C++ support entirely on the
Blackfin architecture in the internal toolchain backend.

This will avoid a significant number of Blackfin build failures, that
occur when building C++ packages.

3897ded714 toolchain: Bump ARC tools to arc-2016.09-eng007 and enable PIE
As described at:
4520524ba0
this commit continues a series of updates of ARC tools.
This time we're updating tools to arc-2016.09-eng007 tag plus a
couple of fixes on top of it that will all make its way in the
next engineering build.

We hope this patch will cure most buildroot ARC failures as it
contains important fixes:

1) PIE fix. We have added PIE support to ARC toolchain at last.
So that should prevent breakage of many packages. As ARC now
supports PIE we remove ARC from BR2_TOOLCHAIN_SUPPORTS_PIE
exclusion in toolchain/Config.in file.

2) Assembler fix. This patch also have changes that fixes frequent
assembler failures, e.g.:
http://autobuild.buildroot.net/results/543/5430b902d900943a34c1888e7e410bd5df367bc2//

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

c101f1b1b8 gcc: add hidden symbol for defaults
Some architectures, f.e. Blackfin doesn't support to configure GCC with
--with-cpu to set some CPU specific default CFLAGS (-mcpu=foo). Use a
hidden config symbol to give a hint which architecture supports it,
otherwise add defaults to toolchain wrapper for internal toolchains.

Idea from Thomas Petazzoni.

4520524ba0 toolchain: Bump ARC tools to arc-2016.09-eng005
With this commit we're starting a series of updates of ARC tools.
Significantly rewritten arc-2016.03 tools introduced way too many
problems highlighted by Buildroot autobuilder. Now in attempt to
resolve as many issues as possible by the time final release of
arc-2016.09 tools is cut we'll be executing arc-2016.09 series
with engineering snapshots like this one.

We decided to go this way instead of applying separate patches here
and there because ongoing development introduces quite a lot of
changes and separate patches are not practical in Buildroot.

Moreover this will give us very clean visibility of number of
issues we see (hopefully it will decrease over time).

One of the important changes introduced in this engineering build
is initial set of changes for proper support of PIE on ARC in terms
of both building on host and running on ARC target. I expect some
PIE-related build breakages to go away and new ones will be treated
as the high-priority issues to be fixed ASAP.

For now we only update Binutils and GCC while keeping 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 one of the first engineering builds of
arc-2016.09 series and it might have all kinds of breakages,
please don't use it for production builds.
