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.

Since <package>-rebuild implies <package>-reinstall and
<package>-reconfigure implies <package>-rebuild, it is confusing
to mention the make and make <package> commands when describing
the restart of the configuration, compilation and installation of
the package.
Therefore remove the ", followed by +make+ or +make <package>+"
portions in the "8.3. Understanding how to rebuild packages" section,
and add a new paragraph clarifying how to include the rebuilt package
in the filesystem image, if that is necessary.

Back in commit 025b863e6f, the option
BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS was introduced, to
separate the option that host packages needing Rust should depend on
(BR2_PACKAGE_HOST_RUSTC_ARCH_SUPPORTS) from the option that target
packages needing Rust should depend on
(BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS).
Since the example in the manual is showing a target package, we must
use BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS.

meson does not allow passing path to helper programs (e.g. pkgconfig)
using variables in the environment. Instead, it insists that those paths
be defined in the cross-compilation.conf file, in the [binaries]

As such, allow packages to declare such a list of arbitrary entries to
add in the [binaries] section.

Currently, the packages are sorted smallest first, and biggest last
(with unknown and others second-to-last and last, resp.).
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).

Now that the two (all of them!) br2-external related files are generated
in the same location, it makes sense they are named after the same
pattern.
When initial support for (then single) br2-external trees was added back
in a4239f7fd1 (core: introduce the BR2_EXTERNAL variable), it was not
clear-cut why that file was not named with a br2 prefix.
So rename it now.

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.
