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.

Since uClibc-ng commit cde74b83f9b2 "ARC: remove special CFLAGS/LDFLAGS handling"
i.e. starting v1.0.23 CONFIG_ARC_CPU_xx options are not used.
Instead uClibc relies on toolchain defaults or build-system CFLAGS
for selection of ARC-specific code (i.e. distinguishes between
ARCompact and ARCv2 ISAs).
So we drop corresponding quirks from Buildroot as well.

MIPS supports two different NaN encodings, legacy and 2008. Information
about MIPS NaN encodings can be found here:
https://sourceware.org/binutils/docs/as/MIPS-NaN-Encodings.html
NaN legacy is the only option available for R2 cores and older.
NaN 2008 is the only option available for R6 cores.
R5 cores can have either NaN legacy or NaN 2008, depending on the
implementation. So, if the user selects a generic R5 target architecture
variant, we show a choice menu with both options available. For well
known R5 cores we directly select the NaN enconding they use.

In order to avoid having to bring libintl from gettext whenever you
want to build a program that needs it, uClibc-ng now provides a stub
implementation of the gettext functions in uClibc-ng itself. This
brings uClibc-ng in the same situation as musl.
This will fix a lot of build failures related to static linking with
libintl, and generally is a first step to simplify our gettext
handling.

Since uClibc-ng v1.0.20 we can force libc to either use llock/scond
instructions for atomic ops or if those are missing use kernel-assisted
emulation. By default atomics are used so we disable that feature in
libc if we build for a target without LLSC.
This allows us to build and use NPTL on ARC750 for example which was not
possible before.
