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

.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.

The download infra now knows to look for per-version hash files, so we

The Qt5 packages may have different licensing terms between the two
versions we support, and in some cases, those different terms are
expressed in similarly named files, like files named plain 'LICENSE' for
example.
Similarly, glibc also has different license files, especially since the
arc version still has libidn, which got dropped from upstream.
This is problematic, because, in a .hash file, we can't store two
different hashes for the same file. We've started to handle this case by
moving the licenses hashes to the per-version sub directories.
However, the hashes for the downloads are still stored inside the non-
versioned hash file of the package, which is not totally coherent: if we
have a per-version hash file, it should list all the hases for that
version, downloads included, and there should be no unversioned hash
file.
In preparation for this, we duplicate the downloads hashes from the main
hash files, and into the versioned ones. Once the download infra learns
to look for those hashes in these per-version subdirs, we'll remove the
unversioned hash files.
Note that, now that we have versioned hash files, the main hash files
will not be used to check license files, so we can already drop the
hashes for license files from the main hash files.
Note also that there are a few other packages for which we support
different versions (binutils, gcc, gdb, lua, xserver_xorg-server,
uboot), but none of those have different licensing terms due to the
version. Qt5 and glibc are alone in this case.

glibc is not using the autotools-package infrastructure, so we are
calling the ./configure script manually. Currently, the few autoconf
cache variables are passed as arguments to the ./configure script,
while we pass them through the environment in the autotools-package
infrastructure.
So let's pass them in the environment, and use a GLIBC_CONF_ENV
variable to store them. This will allow in a follow-up commit to
conditionally add more autoconf cache variables to the glibc build.

Currently, we do a full git clone of the repository, which takes quite
some time, especially on slow networks.
This was done like that because the initial patch was using the official
repository as the source of the download, and that repository did not
offer remotely-generated tarballs.
But now we've switched to using a mirror on github, which does provide
such a tarball, which provides faster downloads.
Use that.
However, the tarball from github differs from the one we were generating
locally, because the paths inside are different. WE used to create a
archive with paths starting with glibc-glibc-2.26-73-g4b692dfb95[...],
while github does away with the git-describe prefix, and generates paths
that start with just glibc-4b692dffb95[...]. The content are exactly
identicall (checked with a diff), though.

glibc upstream has ruled against doing regular point-releases, but they
do have a lot of interesting and important fixes for regressions and
security.
Backporting each patch, or cherry-picking individual patches is off
limits for us, so we just switch to using the currently-latest HEAD of
the maintenance branch instead.
The version number is obtained with:
$ git describe --match 'glibc-*' --abbrev=40 origin/release/2.26/master
The alternative options were:
- download the tarball from the git tree
--> does not work; not an option
- download the 2.26 tarball, and bundle the individual patches in
Buildroot
--> maintenance of patches is a burden; not an option
- download the 2.26 tarball, maintain the list of patches to download from
the git tree
--> not an option for the same reason
So we end up just doing a git clone. The git tree is today about ten
times the size of the tarball, so a rough estimate makes it at about ten
times the download time.
Also upstream doesn't officially provide an https download location [1].
There is one but it's not reliable, sometimes the connection time out and
end-up with a corrupted git repo:
fatal: unable to access 'https://sourceware.org/git/glibc.git/': Failed to connect to sourceware.org port 443: Connection timed out
So switch to using a git mirror from github which is updated once a day [2].
This allow at the same time to clone the git repository faster.
Note: The glibc 2.26 patches are not kept for the arc toolchain since they
are fixing an issue with the new float128 support introduced in x86, x86_64
and powerpc64le.

Finally there's working ARC port of glibc thanks to Vineet and Cuper!
This port is based on pretty recent glibc's master branch and ARC
changes are being reviewed now in glibc's mailing list.
Thus we again have to use sources from our GitHub but as soon as there's
a glibc release with our patches applied we'll switch to upstream releases
and will drop our glibc GitHub repo alltogether.
Note now we cut tags in glibc repo simultaneously with tags
in Binutils and GCC repos and so to make sure everything works in the best
way we plan to update glibc tag together with Binutils and GCC.
Also note as of today ARCompact (AKA ARCv1 ISA) is not supported in glibc
but we plan to fix it soonish so for now we make glibc intentionally
dependent on archs38.
Also note we are not creating directory "2.26" because all patches for glibc
ver 2.26 applies to arc glibc port.

[Thomas: move 3.2 kernel headers dependency to the libc choice in
toolchain/toolchain-buildroot/Config.in file, and added a Config.in
comment about it.]

The input to copy_toolchain_lib_root is not one library, not a list of
libraries, but a library name pattern with glob wildcards.
This pattern is then passed to 'find' to get the actual list of libraries
matching the pattern. Reflect this using an appropriate variable name.
Note: if the root of the buildroot tree contains a file matching one of
these library patterns, the copying of libraries from staging to target will
not be correct. It is not impossible to fix that, e.g. using 'set -f', but
maybe it's not worth it.

On some architectures (namely x86-64), glibc may provide a libmvec
library since glibc 2.22, which programs built with gcc OpenMP support
might get linked to.
In order for these programs to work on the target, we need to copy
this library to the target filesystem.
This commit takes care of this for the glibc package (used for the
internal toolchain backend). Note that libraries listed in
GLIBC_LIBS_LIB are silently ignored if they don't exist. Therefore, we
don't need to have any condition on the architecture or glibc version.
For more details on libmvec, see
https://sourceware.org/glibc/wiki/libmvec.
Fixes bug #9111.
