Currently, we are using a shell script called genext2fs, that
impersonates the real genext2fs. But that script does much more than
just call genextfs: it also calls tune2fs and e2fsck.
Because it impersonates genext2fs, we can not easily add new options,
and are constrained by the genext2fs options.
But it turns out that, of all the options supported by the real
genext2fs, we only really care for a subset, namely:
- number of blocks
- number of inodes
- percentage of blocks reeserved to root
- the root directory which to generate the image from
So, we introduce a new host package, mke2img, that is intended to
eventually replace genext2fs.sh.
This new script is highly modeled from the existing genext2fs.sh, but
was slightly refreshed, and a new, supposedly sane set of options has
been choosen for the features we need (see above), and some new options
were added, too, rather than relying on the arguments order or
environment variables:
-b <nb-blocks> number of blocks in the filesystem
-i <nb-inodes> number of inodes in the filesystem
-r <pc-reserved> percentage of reserved blocks
* -d <root-dir> directory containing the root of the filesystem
* -o <img-file> output image file
-G <ext-gen> extfs generation: 2, 3, or 4 (default: 2)
-R <ext-rev> ext2 revision: 0 or 1 (default 1)
-l <label> filesystem label
-u <uid> filesystem UUID; if not specified, a random one is used
* Mandatory options
Since the upstream e2fsprogs are expected to release a new mke2fs that
will be able to generate a filesystem image from a directory, we then
will be able to replace all the logic in mke2img, to use mke2fs instead
of the (relatively fragile) combination of the three tools we currently
use.
An entry is added for it in the "Host utilities" menu, so it can be
selected for use by post-{build,image} scripts. The ext2 filesystem
selection is changed to select that now.

In some situations, users may want to tweak the dynamic section of the
binaries (for example to add/set the RPATH to $ORIGIN/../lib).
Because it is not trivial to do it properly from the Buildroot
infrastructure, allow those users to use patchelf (e.g. from a
post-build script) to tweak binaries.
patchelf is able to:
- modify an existing DT_RUNPATH tags
- add a DT_RUNPATH tag if not already present
- do the above to the DT_RPATH tag, too
- set the path to the interpreter
- remove DT_NEEDED tags
- query a binary for the DT_RUNPATH/DT_RPATH tag, or for the
interpreter path
Does not really fix#7172, but this is an appropriate workaround.

To keep things consistent, this is done for Config.in.host there, even
though we don't have sub-menus there at the moment.

E2tools is a simple set of GPL'ed utilities to read, write, and
manipulate files in an ext2/ext3 filesystem. These utilities access a
filesystem directly using the ext2fs library.

github helper, add support for host version.]

Useful for for-build scripts to call parted, eg. to generate
partition tables and such automatically.
Since the primary goal is to use parted within scripts, we
do not need readline, so it is forcibly disabled.
Also, it does look unlikely that we need to manipulate LVM
volumes, so we forcibly disable support for the device-mapper.

genext2fs is built only if the user selected an ext2 root filesystem.
However, some use-cases can't live with the full target/ dir on the
root filesystem, and requires separate partitions (eg. for /usr).
In this case, the user would not select an ext2 root fs in the
Buildrooot menu, and would only generate a tarball of the rootfs.
This tarball would then be used from a post-image script to build
the actual required FSes.
But then, genext2fs is not built, since the ext2 root FS was not
selected.
As for the other filesystem generators, provide a host variant of
genext2fs (genext2fs is already host-package aware, so only needs
adding a Kconfig entry).

Most of the host packages don't have to be exposed to the user as they
are only used as build dependencies of target packages.
However, some host utilities, such as flashing utilities, image
creation programs, specific debuggers, might be useful and should be
presented to the user.
Therefore, we have a new global menu, which lists those host
utilities. These utilities are described in package/*/Config.in.host
files, which will be sourced by package/Config.in.host.
