Currently, the linux kernel will apply some fixups on its .config file,
based on whether some packages are enabled or not. That list of
conditional fixups is getting bigger and bigger with each new package
that needs such fixups, culminating with the pending firewalld one [0].
Furthermore, these fixups are not accessible to packages in br2-external
trees.
Add a new per-package variable, that packages may set to the commands to
run to fixup the kernel .config file, which is added at the end of the
linux' own fixups.
This opens the possibility to write things like;
define FOO_LINUX_CONFIG_FIXUPS
$(call KCONFIG_ENABLE_OPT,BLA)
endef
Of course, it also opens the way to run arbitrary commands in there, but
any alternative that would be declarative only, such as a list of
options to enable or disable (as an example):
FOO_LINUX_CONFIG_FIXUPS = +BAR -FOO +BUZ="value"
.. is not very nice either, and such lists fall flat when a value would
have a space.
For packages that we have in-tree, we can ensure they won't play foul
with their _LINUX_CONFIG_FIXUPS. For packages in br2-external trees,
there's nothing we can do; users already have the opportunity to hack
into the linux configure process by providing LINUX_PRE_CONFIGURE_HOOKS
or LINUX_POST_CONFIGURE_HOOKS anyway...
.. which brings the question of why we don't use that to implement the
per-package fixups. We don't, because _PRE or _POST_CONFIGURE_HOOKS are
run after we run 'make oldconfig' to sanitise the mangled .config.

With autoconf packages, we often specify ac_cv_func_... cached values to
avoid runtime checks during configure. With meson the equivalent is
setting properties in cross-compilation.conf which we cannot do in
Buildroot at the moment.
For example, libglib2 used to set ac_cv_func_printf_unix98 and
ac_cv_func_vsnprintf_c99 so that the system printf could be used, but
with the conversion to meson these checks fail and the gnulib fallback
is used.
Add infrastructure in the same way as FOO_MESON_EXTRA_BINARIES to allow
per-package modification to the cross-compilation properties.

This provides generic functions for Qt5 qmake based packages. It will
make it possible to remove lots of redefinition of
QT5_xxx_{CONFIGURE|BUILD|INSTALL_STAGING}_CMDS. Additionally it
provides a generic target install method which will make most of the
package specific commands obsolete.
This is done by re-running the install step of the qmake generated
Makefile with the package build directory prepended (to the
staging/host path). Even though this does create lengthy pathes it
allows for easy separation of the staging files from the host destined
files by just omitting the resulting BUILD_DIR+HOST_DIR path from the
following rsync call to the real target folder. The cleanup of many
files we dont want in target is deferred to the target-finalize
step. In addition to what's being removed already, we also have to
cleanup some Qt5 specific files (prl) and the documentation directory.
This approach was chosen over copying all files recorded in the pkg-files-list
after some discussion which Thomas Petazzoni summed up:
"We don't yet use pkg-files-list really as part of the build
process anywhere, I feel a bit more comfortable at this point with what
Andreas is proposing."
Thanks to this infrastructure, it will be possible to get rid of the
many conditional install commands because qmake already takes care of
this when generating the Makefile install targets with the given or
autodetected configure options of each package.
However, custom install steps may have to remain in cases where a
particular Buildroot option has no corresponding setting in the
packages configuration options.

since v234 upstream recommands using systemctl preset-all to enable units.
* add a buildroot specific preset file
* use that file to disable getty@tty1
* make systemd depend on host-systemd
* remove all link-creating code that systemd does for us.
Most packages will not be affected by this change, but a few packages
were installing units without manually enabling them. Those packages
will now be automatically enabled.
The fact that those packages were not enabled is almost certainly a bug,
but it is a change of behaviour that needs to be reported
host-systemd also builds udevadm for the host. That means we no longer
need to depend on host-eudev to provide udevadm (that would conflict).

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.
