Release notes:
We are very sorry to have to report that a problem was found with the
GNU Binutils 2.36 release. It turns out that it contained a small
portion of code that was not covered by an FSF copyright assignment.
So we have created a replacement release - 2.36.1 - with that code
removed.
In addition we found that a fix for a theoretical security
vulnerability[1] was itself broken and could result in the archiver
program "ar" misbehaving. So we have chosen to revert the fix from
the 2.36.1 release whilst the problem is properly resolved.

Now that 2.36.x has been added, that 2.35.x is the default version,
drop support for 2.33.x.
Note that we keep binutils 2.32.x as it is the latest version that
works for FLAT binaries (used on noMMU platforms).

Binutils 2.29 and 2.30 are affected by a bug in ADR and ADRL
pseudo-instruction [1] that was fixed in Binutils 2.31 [2].
* The ADR and ADRL pseudo-instructions supported by the ARM assembler
now only set the bottom bit of the address of thumb function symbols
if the -mthumb-interwork command line option is active.
Due to this issue, we were default to binutils 2.28 for ARM Thumb. But
now that the issue has been fixed in binutils 2.31 and that this
version is the default, the special casing to use 2.28 is no longer
needed.

As reported by [1], SSP support is missing in the Buildroot toolchain
for microblaze even if it's requested by selecting
BR2_TOOLCHAIN_HAS_SSP config option.
In Buildroot, we are using libssp provided by the C library (glibc,
musl, uClibc-ng) when available. We are not using libssp from gcc.
So for a microblaze glibc based toolchain, the SSP support is enabled
unconditionally by a select BR2_TOOLCHAIN_HAS_SSP.
BR2_microblazeel=y
BR2_TOOLCHAIN_BUILDROOT_GLIBC=y
BR2_KERNEL_HEADERS_4_14=y
BR2_BINUTILS_VERSION_2_30_X=y
BR2_GCC_VERSION_8_X=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
While building the toolchain, we are building host-binutils which
provide "as" (assembler) and host-gcc-initial wich provide a
minimal cross gcc (C only cross-compiler without any C library).
When SSP support is requested, gcc_cv_libc_provides_ssp=yes is
added to the make command line (see [2] for full details)
With this setting, the SSP support is requested but it's not available
in the end and the toochain build succeed.
When the microblaze toolchain is imported to Biuldroot (2018.05) as
external toolchain with BR2_TOOLCHAIN_EXTERNAL_HAS_SSP set, the build
stop with :
"SSP support not available in this toolchain, please disable BR2_TOOLCHAIN_EXTERNAL_HAS_SSP"
The test is doing the following command line:
echo 'void main(){}' | [...]/host/bin/microblazeel-linux-gcc.br_real -Werror -fstack-protector -x c - -o [...]/build/.br-toolchain-test.tmp
cc1: error: -fstack-protector not supported for this target [-Werror]
When we look at the gcc-final log file (config.log) we can see this
error several time when using the minimal gcc (from host-gcc-initial).
So Why the minimal gcc doesn't support SSP?
When we look at the gcc-initial log file (config.log) we can see an
error with 'as':
configure:23194: checking assembler for cfi directives
configure:23209: [...]microblazeel-buildroot-linux-gnu/bin/as -o conftest.o conftest.s >&5
conftest.s: Assembler messages:

.cfi_same_value 1
.cfi_def_cfa 1, 2
.cfi_escape 1, 2, 3, 4, 5
.cfi_endproc
This is the only relevant difference compared to a nios2 toolchain where
libssp is enabled and available (nios2 is an example).
"CFI" stand for "Control Flow Integrity" and it seems that SSP support
requires CFI target support (see [3] for some explanation).
The SSP support seems to depends on CFI support, but the toolchain
infrastructure is not detailed enough to handle the CFI dependency.
The NiosII toolchains built with binutils < 2.30 are also affected by
this issue.
This patch improve the toolchain infrastructure by adding a new
BR2_PACKAGE_HOST_BINUTILS_SUPPORTS_CFI blind option
Disable SSP support for microblaze entirely.
Disable SSP support for nios2 only with Binutils < 2.30.

Commit 17f352ac (package/binutils: default to 2.29 for Cortex-M targets)
made the default version 2.28 (and not 2.29!) when the target is an
arm-v7m CPU.
However, the real trigger is compilation in Thumb mode, not the fact
that the target is v7m.
The fact that it was noticed on a v7m target is because Thumb is the
only mode valid on those CPUs.
Tighten the defaults to 2.28 for Thumb and Thumb2 modes.

As of today quite a lot of ARC stuff got merged in upsream
such that we may finally use upstream realease for building
and even running Linux kernel and rootfs built with vanilla
binutils.
Essentially upstream release is still a bit behind our
GitHub-based releases but let's try to use vanilla version
and if we're lucky enough with just a small set of back-ported patches
we'll be able to use vanilla release(s) for everything in Buildroot.
