Dracut is the tool used by desktop distributions to build initrds.
In the embedded world, it can be very useful, too, for instance when
wanting to create an initramfs for a system recovery mode.
Whereas it is definitively possible to achieve this with buildroot, the
process is to have a dedicated buildroot configuration for that, and
perform a full build. Instead of doing that, dracut can pick the needed
binaries/shared libraries, configuration files, or kernel modules from
the 'target' directory.
The advantage is to save build time, and also to have a consistency
between the packages versions taken for the recovery and the production
filesystem.
The principle of dracut is based on the so-called 'dracut modules'. The
modules determine what will be included in the initramfs. For example,
one of dracut's modules checks the kernel modules that are included and
also includes the corresponding firmware blobs.
On the host, they are on host/lib/dracut/modules.d
Each directory as a prefix number for the order of execution, and
at least a "module-setup.sh" script.
Dracut sources all of them, and typically calls the "check()" function,
which is the placeholder for required binaries (that are aimed to be
polulated in the initrd), then the "depends()" function, that lists
other modules to depend on, and the "install()" function, that makes
the actual work.
Dracut was initially thought to work with systems using systemd,
but it can also work without it. Do to so, every "systemd-xxx"
module must be disabled in the dracut configuration file. For
convenience, the 05busybox-init module is provided, to support
busybox init system. Note that this module should *not* be enabled when
using systemd init. It is therefore only installed if busybox init is
selected.
Musl and uClibc make assumptions about the existence of some symlinks
that are not discoverable with readelf. Therefore, another module
05libc-links is provided that creates those links. The module is
installed regardless of which libc is used - the script itself discovers
if the links need to be installed based on which libc is found.

This is perhaps the most controversial change for Buildroot that can
be written in a two-liner.
Historically, we have used uClibc as our default C library, as
Buildroot was created initially as a test-bed for uClibc, and also
because uClibc made a lot of sense for embedded Linux systems, due to
its smaller size and fine-grained configurability.
Since then, the landscape of embedded Linux systems has changed. Even
though Buildroot happily supports really low-end devices, the vast
majority of Buildroot users are quite certainly running the resulting
system on a reasonably powerful platform, with significant amount of
RAM and storage. In this context, the benefits of uClibc are no longer
that much relevant, and glibc causes less "troubles". Therefore, this
patch proposes to use glibc as our default C library when using the
internal toolchain backend instead of uClibc.
Of course, we will keep the support for uClibc, which remains an
important C library choice, for space-constrained systems, or simply
for architectures that are not supported by glibc.

The Freescale extract helper was introduced before Freescale was part
of NXP. Nowadays, we also have NXP packages, and they do use the same
archiving format.
Rename the helper under the now more generic NXP name, so that it is
more logical to also use it for NXP packages. We do not retain the old
Freescale-based name, because we should no longer add Freescale-named
packages; they would most probably be introduced under the NXP name.

This option was needed to build versions of GDB < 10.x. As we just
dropped support for GDB 9.x, this logic can now be removed.
The special case to configure just gdbserver was only valid for gdb<10,
but was guarded by !GDB_TOPLEVEL (which was equivalent to gdb<10).
GDB_TOPLEVEL is now always true, so we can't hit that special case
anymore.

The handling of the GMP dependency needs a bit of change. Until now,
the GMP dependency was needed when building full GDB (host or target)
in version 11.x or 12.x, so we were explicitly checking whether those
versions were enabled.
Now that only GDB 10.x and the ARC-specific version of GDB are the
only remaining ones not needing GMP, we invert the logic: only those
two versions do not trigger the addition of the GMP dependency.

libgit2 is currently a library without any reverse dependencies so the
missing atomic symbols do not cause build failures yet.
libgit2 uses the atomics intrinsics on gcc >= 4.7 and the sync
intrinsics on previous gcc versions. Since gcc 4.9 is the new
minimum, ignore the sync intrinsics requirements.
The next version of libgit2 will also build a binary, which will
expose the problem.

binutils 2.39 added support for gprofng, a new profiler (see
https://www.phoronix.com/news/GNU-Profiler-gprofng).
This new profiler is enabled by default, but it requires bison on the
host.
In order to handle this, this commit:
- Adds a new option BR2_BINUTILS_GPROFNG, which allows to
enable/disable gprofng in host-binutils
- Unconditionnally disables gprofng for the target binutils, based on
the idea that in a Buildroot context the analysis of profiling data
is generally done on the host system. This can of course always be
revisited later by adding a new option to the target binutils
package.

Remove broken elf2flt patch:
package/elf2flt/0003-elf2flt-fix-.eh_frame-section-handling.patch
The patch modifies main(), but does not perform a similar change in
output_relocs(), which might cause sectionp in output_relocs() to be
initialized with an invalid address, causing random memory to be
overwritten.
This leads to a segfault when linking e.g. busybox for m68k.
We cannot perform a similar change in output_relocs(), since at this
point in time, data_len will always be non-zero.
Revert this patch completely, so that we can add a working patch.
Note that even with this patch reverted, elf2flt is still broken
on archs like m68k and xtensa, resulting in the fatal error:
