Currently, the formatting we impose on the _LICENSE variable requires
that we also use the rarely used := assignment operator, which makes
the _LICENSE variable the only variable that users have to write with
this operator.
This really departs from the simplicity and consistency of using the
append-assignment, which we use for every other variable.
This is because the append-assignment operator surreptiously
introduces a space between the original value and the appended one. But
we can use this knowledge, to match any instance of a space followed by
a comma, and turn it into a single comma.
This allows users to now have a consistent use of the '=' and '+='
operators we use everywhere else in .mk files.

Currently, we only require a gcc 4.4 version, which now is pretty old
(released in April 2009). This requirement is not even tested nowadays,
with our oldest autobuilder having a 4.7 version only.
And even then, 4.7 is still old enough that it prevents us from
upgrading some packages. For example cmake 3.10+ requires C++11
constructs that were only added in gcc 4.8 (when C++11 support was
finally completed in gcc).
So, update our requirements for gcc to at least 4.8.

Currently, the packages are sorted smallest first, and biggest last

Add an option to invert the ordering (but keeping unknown and others at
their current positions).
This has the nice side effect that we can now control the colours
assigned to the biggest package(s), as the colours are cycled from the
first to the last. Currently, the biggest packages gets a redish colour,
which is appropriate, but the second gets a greenish one, which is not
as appropriate (but changing that can come later).

When dealing with embedded devices, storage is more often than not some
kind of flash device, on which the memory is usually counted as powers
of 1024 instead of powers of 1000. As such, people may prefer reports
using IEC prefixes [0] instead of the SI prefixes.
Add an option to that effect.
We use argparse's ability to use custom actions [1] [2], to provide a
set of options that act on a boolean, but has a single help entry and
internally ensures consistency of the settings. We could have been using
the more conventional store_true/store_false actions instead, but that
would have meant either two help entries, one for each set of options,
and/or some logic after parse_args() to check the validity of the
settings.

Currently, we group packages that contribute less then 1%, into the
"Other" category.
However, in some cases, there can be a lot of very comparatively small
packages, and they may not exceed this limit, and so only the "Others"
category would be displayed, which is not nice.
Conversely, if there are a lot of packages, most of which only so
slightly exceeding this limit, then we get all of them in the graph,
which is not nice either.
Add a way for the developers to pass a different cut-off limit. As for
the dependency graph which has BR2_GRAPH_DEPS_OPTS, add the environment
variable BR2_GRAPH_SIZE_OPTS to carry those extra option (in preparation
for more to come, later).

Meson does not allow to pass CFLAGS/LDFLAGS/CXXFLAGS via the environment
or via command-line arguments or options (instead, those flags from the
environment are passed to the host compiler, which is seldom what we
need). The only way to pas those flags is via the cross-compilation.conf
file.
Add LIBFOO_CFLAGS, LIBFOO_LDFLAGS and LIBFOO_CXXFLAGS variables to allow
packages to provide their own flags, possibly overriding the generic
ones entirely, as we allow for other infras. Those per-package flags will
then be used to generate the per-package cross-compilation.conf.
This means that the meson infra is the first and only infra for which
FOO_CFLAGS, FOO_LDFLAGS, and FOO_CXXFLAGS are meaningful, while for the
other infras, they are just variables private to the package itself.
Instead of naming those variables after the meson infra (e.g.
FOO_MESON_CFLAGS), we name them with a generic name, as maybe, just
maybe, we could also change the other infras to also recognise those
variables.
Just like for the HOST_MESON_SED_CFLAGS etc., we need to add auxiliary
variables to do convert the shell-formatted argument list into the
JSON-formatted list that meson expects. We can't use a pure-make
construct because the CFLAGS can contain quoting that needs to be
expanded by the shell. Similarly, we need a condition on the strip'ed
variable to avoid passing empty arguments.
To mimic this feature for packages that are built from the SDK, we also
install a templatised version of cross-compilation.conf, with three new
placeholders for custom flags. If a user wants to build a package that
needs custom flags, they can use that template to generate a per-package
cross-compilation.conf.

The hidden Config.in option BR2_PACKAGE_HOST_GO_ARCH_SUPPORTS name is
not very clear as to whether it says whether Go is available for the
target architecture or the host architecture.
Until now, this was fine since there was support for host Go
packages. But as we are about to introduce support for building host
Go packages, we need to clarify the meaning of
BR2_PACKAGE_HOST_GO_ARCH_SUPPORTS. Since it says whether the target
architecture has support for Go or not, we rename it to
BR2_PACKAGE_HOST_GO_TARGET_ARCH_SUPPORTS.
And since BR2_PACKAGE_HOST_GO_CGO_LINKING_SUPPORTS is tightly related,

For about two years, a legal entity called "Buildroot Association" was
created in France to support the Buildroot project. Until fall 2018,
this legal entity has not been used. In fall 2018, we started using it
in order to receive donations from companies in order to organize the
Buildroot Developers Meeting that took place before the Embedded Linux
Conference Europe 2018 in Edinburgh.
This commit creates a new page on our web site that documents the
existence of this Buildroot Association, and details how to become a
member. Both individuals and companies can become members.
It is worth stating that the Buildroot Association does not control
the Buildroot project: it remains a fully open-source and
community-driven project. The Buildroot Association only serves as a
legal entity to handle donations and money needed to organize the
Buildroot Developers Meeting, and pay for a few expenses related to
the project (such as domain names).

Some users of kconfig need some packages to be built before their
kconfig infra be used.
For example, the linux kernel, starting with 4.16, needs flex and bison
to generate the parser code. Furthermore, starting with 4.18, it will
also need the cross-compiler before parsing the kconfig stuff, because
that calls the compiler to check its features.
Currently, this is broken, even the flex/bison ones, even though they
are listed, because there is no way to define dependencie that are
guaranteed before the (visual) configurators. For example:
$ make distclean
$ make menuconfig
--> enable the linux kernel, choose a defconfig, save, exit
$ make linux-menuconfig
[...]
HOSTCC scripts/basic/fixdep
HOSTCC scripts/kconfig/conf.o
YACC scripts/kconfig/zconf.tab.c
/bin/sh: bison: command not found
LEX scripts/kconfig/zconf.lex.c
scripts/Makefile.lib:196: recipe for target 'scripts/kconfig/zconf.tab.c' failed
make[3]: *** [scripts/kconfig/zconf.tab.c] Error 127
make[3]: *** Waiting for unfinished jobs....
/bin/sh: flex: command not found
scripts/Makefile.lib:188: recipe for target 'scripts/kconfig/zconf.lex.c' failed
make[3]: *** [scripts/kconfig/zconf.lex.c] Error 127
Makefile:528: recipe for target 'rpc_defconfig' failed
make[2]: *** [rpc_defconfig] Error 2
linux/linux.mk:511: recipe for target '/home/ymorin/dev/buildroot/buildroot/output/build/linux-4.17.11/.config' failed
make[1]: *** [/home/ymorin/dev/buildroot/buildroot/output/build/linux-4.17.11/.config] Error 2
Makefile:79: recipe for target '_all' failed
make: *** [_all] Error 2
So, we introduce a new type of dependencies for kconfig-based packages,
that are guaranteed to be built and installed before the (visual)
configurators are called.
Since those dependencies are phony targets and therefore always out of
date, a normal dependency would cause the .config target to be rebuilt
on each invocation of make. So we use an order-only pre-requisite, like
is done for the patch dependency.

Currently, the wording in the manual instructs the user to generate a
tarball from "the contents of the +output/host+ directory".
This is pretty confusing, because taken literally, this would amount to
running a command like:
tar cf my-sdk.tar -C output/host/ .
This creates a tarbomb [0], which is very bad practice, because when
extracted, it creates multiple files in the current directory.
What one really wants to do, is create a tarball of the host/ directory,
with something like:
tar cf my-sdk.tar -C output host/
However, this is not much better, because the top-most directory would
have a very common name, host/, which is pretty easy to get conflict
with when it gets extracted.
So, we fix that mess by giving the top-most directory a recognisable
name, based on the target tuple, which we also use as the name of the
archive (suffixed with the usual +.tar.gz+.) We offer the user the
possibility to override that default by specifying the +BR2_SDK_PREFIX+
variable on the command line.
Since this is an output file, we place it in the images/ directory.
As some users expressed a very strong feeling that they do not want to
generate a tarball at all, and that doing so would badly hurt their
workflows [1], we actually prepare the SDK as was previously done, but
under the new, intermediate rule 'prepare-sdk'. The existing 'sdk' rule
obviously depend on that before generating the tarball.
We choose to make the existing rule to generate the tarball, and
introduce a new rule to just prepare the SDK, rather than keep the
existing rule as-is and introduce a new one to generate the tarball,
because it makes sense to have the simplest rule do the correct thing,
leaving advanced, power users use the longest command. If someone
already had a wrapper that called 'sdk' and expected just the host
directory to be prepared, then this is not broken; it just takes a bit
longer (gzip is pretty fast).
Update the manual accordingly.

The manual is GPL-2, and points to the COPYING file in the repository.
When we do a rendering of the manual for a specific version, that URL
is currently always poitning to the latest version of the COPYING file.
If we ever have to change the content of that file (e.g. to add a new
exception, more clarifications, a license change, or whatever), then
an old manual would point to that newer version, which would then be
incorrect.
Include the sha1 of the commit in the URL, so that the manual always
point to the tree at the time the manual was rendered, not the time
it is consulted. Contrary to the informative text above, use the full
sha1, not the shortened one.

For various reasons, we've always suggested users to avoid using a
branch as version string for their packages, because it does not work
as a they would expect:
- it is not reproducible, because the branch may change between two
builds that are done at different times;
- it does not even follow the branch, as Buildroot anyway generates
a local tarball, which it will reuse on subsequent builds.
Furthermore, since we fetch and not pull, any existing local branch
is not updated.
Yet, until recently, using a branch name would just work (with the
above limitations): the git tree was cloned, the branch checked out,
and the tarball created.
But with the advent of the git caching, using a branch name does not
work anymore. Indeed, we now do a git-fetch, and that does not create
a local master branch. So we can't check out master, because it does
not exist locally. And for other branches, as noticed above, the local
branch does not get udpated to the remote one.
Furthermore, the local branches are only created by chance, again as a
side-effect of trying to fetch the "special refs".
So, we can't say that we reliably support the use of a branch name.
Update the manual to state that using a branch does not work. Remove
the 'stable' example, as it looked like the name of a stable branch;
instead, replace it with a version string that ressemble a tag.
Fix the layout of the manual by making the version examples an actual
bulleted list.
Note: the above is only entirely true for git. For Mercurial, CVS and
subversion, the status may be mixed, but nonetheless, using branches is
still a bad idea, if at least because it is not reproducible, and
because Buildroot does not even follow the branch. So, we do not
differentiate between the various SCMs, and just flatly state that using
a branch name is not supported.
