It is just included by toolchain/Config.in, and toolchain/Config.in is

Currently the script only checks files inside the package/ directory.
Upcoming patches will enable it for other directories.
In order to reliably test for file names, i.e. the Config.in in the base
directory, normalize the path of files to check to a relative path to
the base directory.
Rename the variable that holds the compiled regexp to better represent
its content and rearrange how it is declared to make easy to later add
new directories to check. As a consequence the files that declare
package infra types would not be ignored anymore, so create a new
variable to list the files intree to be ignored during the check. The
same variable will be used by upcoming patches to ignore other files.
Ignore pkg-*.mk and doc-asciidoc.mk since they are package infra files.
In order to not produce weird results when used for files outside the
tree (i.e. in a private br2-external) add an explicit command line
option (-b) that bypasses any checks that would make a file be ignored
by the path that contains it.
When in this out-of-tree mode, the user is responsible for providing a
list of files to check that do not contain files the script does not
understand, e.g. package infra files.
As a result of this patch, besides the known use:
$ ./utils/check-package package/new-package/*
someone with the utils/ directory in the path can now also run:
$ cd package/new-package/
$ check-package *
or
$ check-package -b /path/to/br2-ext-tree/package/staging-package/*

libbsd builds now almost fine with a musl or uClibc toolchain, except
for one issue introduced in the latest version bump. Upstream commit
22fbd62368c39de8ac5e249d1502d5ac0ffdef30 [1] uses the glibc-only macro
`__GLIBC_PREREQ`. The issue is fixed by the attached patch from upstream,
which fixes the use of `__GLIBC_PREREQ` on non-glibc toolchains.
Backported from:
https://cgit.freedesktop.org/libbsd/patch/?id=1f8a3f7bccfc84b195218ad0086ebd57049c3490
netcat-openbsd is the only package selecting libbsd. However, building

Currently, if the user specifies the path to an existing directory as
the path to the custom (def)config file (FOO_KCONFIG_FILE), then we
happily create a file in there, either 'defconfig' or '.config' (or
whatever the .config is named for that package), depending on whether
we're saving a defconfig or a full config.
So, we could save the file, but then the Buildroot defconfig file that
contains that path would no longer be reusable as-is, because we
interpret that path as a path to a file.
Furthermore, if the directory-portion of FOO_KCONFIG_FILE does not
exist yet, the update would fail, because cp does not create missing
directory components.
So we fix that by adding an explicit test for the directory-ness of the
target file, and then an explicit mkdir to create missing directory
components.

When updating back the (def)config file, the touch command is not very
useful by default, so hide it away.
We do not hide away the cp command, as that could confuse the user under
some circunmstances. For example, when the toolchain does not yet exist,
the uClibc buildsystem will complain multiple times about gcc not being
found, like so:
make[2]: /home/ymorin/dev/buildroot/O/host/bin/i686-buildroot-linux-uclibc-gcc: Command not found
(Note that we can not suppress those warnings, as they are on stderr,
and we still want to see stderr in case of real errors).
So, if we were to hide the cp command, the user could be left confused,
even though we were sucessful in updating back the (def)config file.

Luajit only supports a limited number of architectures, so building it for
the host limits the architectures Buildroot can be used on (E.G. powerpc64
autobuilders).
To fix this, always use host-lua. Slightly rework lua.mk to ensure

Each of the intermediate, per-rootfs target directories, as well as the
intermediate tarball, can take quite some place, and is mostly a
duplication of what's already in target/. The only delta, if any, would
be the tweaks made by the filesystem image generations, but those tweaks
are most probably only meaningful when seen as root.
We normally do not remove intermediate files, but those can be quite
large, and are not directly usable by, nor accessible to the user.
So, get rid of them once the filesystem has been generated.
This does not need to be done in fakeroot.

Currently, some packages may register hooks to be run just before and
just after the generic tarball image is generated, because they need to
prepare the filesystem for read-only or read-write operation.
However, this means that, if any of the hooks or the image generation
fails, the target directory is left in a dangling, inconsistent state.
We fix that by doing a copy of target/, run the hooks on that copy,
generate the generic tarball image out of that, and get rid of the copy.
This way, we can guarantee consistency of the target directory, and we
can even ditch support for post-fs hooks (those that restore target/).

Currently, some filesystems may want to tweak the content of the target
directory, create special device nodes etc... This all means that:
- the content of the target directory for a specific filesystems may
depend on whether another filesystem is enabled or not; for example,
cpio will create a /init script or symlink and a /dev/console node;
- the filesystems can not be built in parallel, because they may change
the content of the target directory while another is being assembled.
Furthermore, the same fakeroot script is executed over-and-over-again
for each filesystem, to create the device nodes, the users and their
homes and files, and setting permissions...
We introduce an intermediate tarball, for which we do the full fakeroot
shebang.
That tarball then serves as the base for the other filesystems, with a
very simple fakeroot script that untars the common tarball, and calls
the actual filesystem image generator on that.
Note that we use a very simple tar command to generate the intermediate
tarball, because we are not concerned with reproducibility of the
archive itself (only of the archived files).

Before we can create an intermediate tarball for all filesystems, we
nedd to move the common dependencies needed to generate that
intermediate tarball, rather than leave those dependencies to each
filesystem.
So, we introduce rootfs-common, which gathers all those common
dependencies.

... and locate that script in a per-rootfs directory.
Just like for ROOTFS, this variable will leak down the dependency tree to
target-finalize and packages - But it doesn't matter as it isn't used
outside fs/.

Like we do for packages with the PKG variable, set ROOTFS to contain the
upper-case name of the rootfs currently being generated.
This will be useful in later patches, when we need more per-rootfs
variables, like a per-rootfs TARGET_DIR for example.
In Makefiles, per-rule variables trickle down the dependency chain, to
all dependencies of that rule, so we have to stop ROOTFS as soon as
we're not in a rootfs. This means we have to stop it at target-finalize
(which is a dependency of all filesystems), and for each package
individually, since some packages (host or target) can be direct
dependencies of filesystems as well.
