675f02fd3f package/pkg-meson: improve generation of cross-compilation file
Removed a few variables, as they were only used to communicate
between the meson package and pkg-meson.mk and are not needed
anymore.

Moved cross-compilation.conf.in out of meson package.

Creating the cross-compilation.conf files for packages is now
using the original template.
To avoid duplicate code, the common sed pattern is stored in
a make variable.

Use explicit Buildroot variables for compiler tools,
and some fixes. (TARGET_LDFLAGS and TARGET_CXXFLAGS
were mixed up with PKG_TARGET_CFLAGS)

dd8f8f8e89 support/misc/relocate-sdk.sh: allow relocating to any directory
Currently, relocate-sdk.sh must be run _after_ relocating the SDK. There
are cases where it is useful to already prepare the SDK _before_
relocating. For example, it allows to prepare a tarball that the user
has to extract to a specific, pre-defined location and nothing more than
that, which is simpler for the user than requiring the script to be run.
In addition, it hides the build directory that was used by the SDK
builder (somewhat).

Add an optional argument to relocate-sdk.sh that gives the target
directory.

5b00c382fc support/utils: make-comma-list does just that, not quoting
Currently, we have two functions that build a comma-separated list
of items; one is double-quoting the items, while the other is
single-quoting them. Their naming is not very consistent.

Besides, in a followup change, we will need to build a comma-separated
list of items that are already double-quoted.

Introduce a macro that does just build a comma-separated list, and
use that in the two other macros; rename the existing macro so the
naming is consistent.

12c7a05da1 utils/test-pkg: add gitlab-ci support
The gitlab-ci support in test-pkg allows to parallelize the test-pkg
work into several gitlab jobs. It's much faster than local serialized
testing.

To trigger this, a developer will have to add, in the latest commit of
their branch, a token on its own line, followed by a configuration
fragment, e.g.:

    test-pkg config:
    SOME_OPTION=y
    # OTHER_OPTION is not set
    SOME_VARIABLE="some value"

This configuration fragment is used as input to test-pkg.

To be able to generate one job per test to run, we need the list of
tests in the parent pipeline, and the individual .config files (one per
test) in the child pipeline. We use the newly-introduced --prepare-only
mode to test-pkg, and collect all the generated .config files as
artefacts; those are inherited in the child pipeline via the
"needs::pipeline" and "needs::job" directives. This is a bit tricky,
and is best described by the Gitlab-CI documentation [0].

We also list those .config files to generate the actual list of jobs to
run in the child pipeline.

Notes:
  - if the user provides an empty fragment, this is considered an error:
    indeed, without a fragment (and the package name), there is no way
    to know what to test;
  - if that fragment yields an empty list of tests, then there is
    nothing to test either, so that is also considered an error.

6fbdf51596 Makefile: Parallelize glibc locale generation
Parallelizes locale generation based on `BR2_JLEVEL` setting.

Locale generation always runs during the finalize stage and can consume
a significant amount of time. Parallelizing it greatly reduces that time
on multi-core machines.

To parallelize it, we first invoke `localedef` for every locale in
parallel with the `--no-archive` option. This creates the intermediate
locale data instead of writing to the finally archive directly.

Then, we invoke `localedef` again once to create the archive from the
intermediate compiled locale data files.

We have to do it this way because `localedef` does not do any locking
when writing to the archive file, so calling it without `--no-archive`
concurrently could result in a corrupt archive file or an archive file
that is missing some locales.

While we're at it, make two additional improvements:
- Remove locale-archive before adding to it. Otherwise, repeated
  applications of target-finalize will keep on growing the file.
- Sort the locales when creating locale-archive so its contents are
  reproducible.

We use `find` to collect the installed locales rather than LOCALES. This
makes it possible for something else (skeleton, overlay, custom package)
to create and install additional locales and still have them added to
locale-archive.

841ee767be core: make it possible to check flake8 like we check package
Move the code to run check-flake8 into the Makefile, like we have for
check-package, so that it is easy to run locally (and not wait for
someone to report a failure from their Gitlab pipelines).

Compared to the existing check from gitlab-ci.yml, the Makefile check
differs in this respect:

  - don't explicitly find *.py files: they are supposed to also be found
    as a result of running 'file' on them;

  - use git ls-tree instead of find: this is supopsedly faster as it
    uses the index rather than readdir();

  - don't output the count of warnings or errors: the output is a single
    integer, which is confusing when there are errors, and even more so
    when there are no, when it is simply '0';

  - don't sort: the output is already stable and independent from the
    locale;

  - don't report the number of processed files: this information is
    rather useless, and getting a hold of it would be more challenging
    in this new code.

Note: ideally, we would want to use --null, --zero, or similar options,
with utilities that generates or parses a files listing.  While git
ls-tree and xargs do support it, it becomes a little bit tricky to use
the --print0 option of file, and then grep in that output (it is not
undoable, but would requires replacing grep+cut with some sed trickery).
Since we do not expect our scripts names to contain funky chars (like
\n or a colon), we just hand-wave away that issue (and the old code was
doing the same assumption too).

2ed3b0a586 gitlab-ci: check all defconfigs on every push
The defconfig check has been introduced by the previous
patch before the building each defconfig but those builds
are done every week or more.

Checking if a defconfig is valid can be done on every
push in the repository since it take few seconds.

This would allow to detect as soon as possible a problem
in a defconfig and eventually avoid breaking the build
while build testing all defconfig.

Introduce a new job template ".defconfig_check" in
gitlab-ci.yml.in and modify the generate-gitlab-ci-yml
to create a job for each defconfig to run the test.

Although, we could have used only one job to do all
tests, using one job per defconfig allow to identify
easily in gitlab which defconfig is falling.

35c5cf56d2 Makefile: make-4.3 now longer un-escapes \# in macros
make-4.3 shipped with a backward incompatible change in how sharp signs
are handled in macros. Previously, up to make 4.2, the sharp sign would
always start a comment, unless backslash-escaped, even in a macro or a
fucntion call.

Now, the sharp sign is no longer starting a comment when it appears
inside such a macro or function call. This behaviour was supposed to be
in force since 3.81, but was not; 4.3 fixed the code to match the doc.

As such, use of external toolchains is broken, as we use the sharp sign
in the copy_toolchain_sysroot macro, in shell variable expansion to
strip off any leading /: ${target\#/}.

Fix that by applying the workaround suggested in the release annoucement
[0], by using a variable to hold a sharp sign.

07f31ee263 support/cmake: Explicitly set CMAKE_SYSTEM
Some packages test for CMAKE_SYSTEM explicitly[1]

CMAKE_SYSTEM is comprised of CMAKE_SYSTEM_NAME and CMAKE_SYSTEM_VERSION.
It defaults to CMAKE_SYSTEM_NAME if CMAKE_SYSTEM_VERSION is not set[2]

At the point CMAKE_SYSTEM_NAME is set to "Linux" CMAKE_SYSTEM is already
constructed. Setting it explicitly ensures that it is the correct value.

This is because we do set CMAKE_SYSTEM_NAME twice, in fact:

  - first in toolchainfile.cmake, so that we tell cmake to use the
    "Buildroot" platform,

  - second, in the Buildroot.cmake platform definition itself, so that
    we eventually behave like the Linux platform.

We also set CMAKE_SYSTEM_VERSION to 1, and so the real CMAKE_SYSTEM
value should be set to Linux-1 if we were to follow the documentation to
the letter.

However, for Linux, the version does not matter, and in some situations
may even be harmful (that was reported in one of the commits that
introduce Buildroot.cmake and toolchainfile.cmake).

9bde598ced infra/utils: add helper to generate comma-separated lists
Add a helper macro that, from a space-separated list of items, returns a
comma-separated list of the quoted items.

This will be useful when we need to generate lists in JSON, later...

Code suggested by Thomas P.

fc8a5f56b9 infra/pkg-cmake: use an obviously-invalid value for CMAKE_SYSTEM_VERSION
In 36568732e4, we expanded toolchain.cmake to also define the value for
CMAKE_SYSTEM_VERSION, as the cmake documentation states that it must be
manually defined when doing cross-compilation [0]:

    When the CMAKE_SYSTEM_NAME variable is set explicitly to enable
    cross compiling then the value of CMAKE_SYSTEM_VERSION must also
    be set explicitly to specify the target system version.

However, the fix in 36568732e4 uses the version of the kernel headers,
assuming that would be the oldest kernel we could run on. Yet, this is
not the case, because glibc (for example) has fallbacks to support
running on kernels older than the headers it was built against.

The cmake official wiki [1] additionally states:

  * CMAKE_SYSTEM_VERSION : optional, version of your target system, not
    used very much.

Folllowed a little bit below, by:

  * CMAKE_TOOLCHAIN_FILE : absolute or relative path to a cmake script
    which sets up all the toolchain related variables mentioned above

    For instance for crosscompiling from Linux to Embedded Linux on PowerPC
    this file could look like this:

        # this one is important
        SET(CMAKE_SYSTEM_NAME Linux)
        #this one not so much
        SET(CMAKE_SYSTEM_VERSION 1)

    [...]

Furthermore, using the kernel headers version can be a bit misleading (as
it really looks like is is the correct version to use when it is not),
while it is obvious that 1 is not really the output of `uname -r` and
thus is definitely not misleading.

Finally, random searches [2] about CMAKE_SYSTEM_VERSION, mostly only
turns up issues related with Windows, Mac-OS, and to a lesser extent,
Android (where it is forcibly set to 1), with issues realted to running
under just Linux (as opposed to Adnroid) mostly non-existent.

Consequently, we revert to using the value that is suggested in the
cmake WiKi, i.e. 1, and which is basically what we also used as a
workaround in the azure-iot-sdk-c paclkage up until d300b1d3b1.

A case were we will need to have a real kernel version, is if we one day
have a cmake-based pacakge that builds and installs a kernel module [3],
because it will need the _running_ kernel version to install it in
/lib/modules/VERSION/, but in that case it will anyway most probably
not be the headers version.
