This commit adds the support for gcc 6. This release allows to remove
a large number of our gcc patches, mainly thanks to the Xtensa and
musl related patches being merged upstream.
Patches kept with no changes:
100-uclibc-conf.patch
301-missing-execinfo_h.patch
810-arm-softfloat-libgcc.patch
830-arm_unbreak_armv4t.patch
840-microblaze-enable-dwarf-eh-support.patch
860-cilk-wchar.patch
890-fix-m68k-compile.patch
Patches dropped because they have been merged upstream, or were
already upstream backports:
120-gcc-config.gcc-fix-typo-for-powerpc-e6500-cpu_is_64b.patch (merged)
850-libstdcxx-uclibc-c99.patch (merged in a different form, see

This change introduces newer ARC toolchain in Buildroot.
That new arc-2015.12 release doesn't bring any significant changes
but mostly is focused on fixes and minor improvements here and there.
Most noticeable changes are:
* GCC: Source update to v4.8.5
* GDB: Updated to upstream 7.10 release.
You may find more info on fixes and improvements in that release at:

I'm happy to update GNU tools for ARC cores to the most recent
arc-2015.06 release.
This release brings following major improvements:
* GCC: source update to v4.8.4
* GCC: C ABI compatibility between MetaWare and GNU toolchains
* uClibc: support for thread local storage and Native Pthread Library (NPTL)
* GDB: updated to version 7.9.1
Also a lot of fixes and improvements has been done, please refer to
https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2015.06
for more details.

Even though this is only RC1 it's been heavily used internally so it should
not be any worse than existing arc-2014.12.
Moreover this relase (and so its RC1) finally delivers support of NPTL
for ARC in uClibc.
That's why it would be good to allow interested users to start trying it
(for example WebKit and apps that use WebKit could be successfully built
and run) also it will be helpful to run that new toolchain through
autobuilder in attempt to find any hidden regressions so we have a solid
toolchain for release.
If there's an interest in that patch more patches will follow with
subsequent RCs and essentially on appearence or relese Buildroot will be
updated with it.

This commit adds support for gcc 5.1 in Buildroot. In terms of gcc
patches, compared to gcc 4.9.x:
* Kept as is, sometimes after minor adjusments:
100-uclibc-conf.patch
301-missing-execinfo_h.patch
810-arm-softfloat-libgcc.patch
830-arm_unbreak_armv4t.patch
840-microblaze-enable-dwarf-eh-support.patch
850-libstdcxx-uclibc-c99.patch
860-cilk-wchar.patch
* Dropped:
110-pr64896.patch
111-pr65730.patch
* Split in multiple parts:
900-musl-support.patch
The patches from Crosstool-NG for muls support are used instead of
one single patch.
* Renamed:
910-gcc-poison-system-directories.patch to
200-gcc-poison-system-directories.patch
920-libgcc-remove-unistd-header.patch to
201-libgcc-remove-unistd-header.patch
Since the 9xx part of the series is now used by the various musl
related patches.
We have tested the following configurations, with a minimal Busybox
system:
* ARM, uClibc-ng
* ARM, glibc
* ARM, musl
* x86, uClibc-ng and uClibc 0.9.33.2
* x86, glibc
* x86, musl
All of the configurations built fine. All the configurations boot fine
in Qemu, except x86/uClibc (either ng or 0.9.33.2), it segfaults when
running init:
devtmpfs: mounted
Freeing unused kernel memory: 300K (c1389000 - c13d4000)
init[1]: segfault at 0 ip b77708c1 sp bfa9bb0c error 4 in ld-uClibc-0.9.33.2.so[b776c000+6000]
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
We'll give some time for the uClibc developers to fix the problem
before taking other measures in Buildroot to exclude gcc 5.1 from a
x86/uClibc configuration.
