This version works with linux kernel 5.0 and newer. It requires
CONFIG_NF_NAT enabled in the kernel configuration, otherwise it fails
to build:

Currently the BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT option is only
available to be selected by another config option. This option controls
if the Linux build system should build the DTB itself, or if buildroot
explicitly calls the Linux Makefile like "make something.dtb".
My use case: I want to build an OpenRISC image with a custom device tree
file. OpenRISC does not support appended DTBs, and I'm not using a
bootloader, but link everything into a single kernel (vmlinux) image.
The kernel option CONFIG_OPENRISC_BUILTIN_DTB allows me to specify a dtb
file, which is typically located in the kernel source tree in
arch/openrisc/boot/dts/NAME.dts.
Since my dts file is not part of the upstream kernel, I have two
options: either patch the kernel to include the DTS file, and then
specify it using the CONFIG_OPENRISC_BUILTIN_DTB option.
Or use buildroot's BR2_LINUX_KERNEL_CUSTOM_DTS_PATH config option to
copy any DTS file to the kernel source tree, and then specify this file
with CONFIG_OPENRISC_BUILTIN_DTB as before.
However, the second option also requries the buildroot option
BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT to be set, otherwise I end up with a
"make -C kerneldir NAME.dts" call, which doesn't work (no such target
exists).
Currently the BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT option exists, but it's
not visible/available. Simply making it available solves the problem for
me nicely.

Sometimes, it is required to call imagemagick from a post-build script
or the likes, so we have to allow the user to enable the host variant
for imagemagick.

>From patch [1] included in kernel >= 5.0:
"The upcoming GCC 9 release extends the -Wmissing-attributes warnings
(enabled by -Wall) to C and aliases: it warns when particular function
attributes are missing in the aliases but not in their target.
In particular, it triggers for all the init/cleanup_module
aliases in the kernel (defined by the module_init/exit macros),
ending up being very noisy.
These aliases point to the __init/__exit functions of a module,
which are defined as __cold (among other attributes). However,
the aliases themselves do not have the __cold attribute.
Since the compiler behaves differently when compiling a __cold
function as well as when compiling paths leading to calls
to __cold functions, the warning is trying to point out
the possibly-forgotten attribute in the alias."
Werror is set by default while building ppc kernel [2], but
some warning can be introduced while building current kernel with
newer compiler (for example building kernel 4.19 with gcc 9.1).
For the same reason why we remove Werror in packages's compiler
flags. Building with Werror is not bulletproof when we start
using a newer compiler that introduce new warnings.
This is the case here.
Also this option is a bit strange since it's specific to ppc kernels:
"The intention is to make it harder for people to inadvertantly
introduce warnings in the arch/powerpc code."
Other kernel developers on other arch may be interested by a
similar/more generic option.
So, It's clearly intended for kernel developers.
Instead of backporting this patch [1] to kernel 4.19, select
unconditionally the Kconfig option CONFIG_PPC_DISABLE_WERROR
that allow to disable Werror.

We currently do the Linux build as follows:
make <imagename>
if modules enabled; make modules; fi
However, Clement Léger recently reported that due to us not using the
"all" target, the GDB scripts that the kernel can build when
CONFIG_GDB_SCRIPTS is enabled are not built, since upstream kernel
commit 67274c083438340ad16c1437caebc84e1253b224 (merged in v5.1) moved
that logic to a separate scripts_gdb target, which is a dependency of
the "all" target.
While we could add some more logic to explicit generate the
"scripts_gdb" target, this logic would fail on Linux < 5.1 for which
this make target doesn't exist.
So instead, let's simplify the build logic, and use:
make all <imagename>
The "all" target automatically depends on "modules" if CONFIG_MODULES
is set, so we no longer need to explicit generate the "modules" target
separately.
As a result of this change, we may generate additional kernel images
compared to what was done previously, but such images would anyway not
be installed, and the additional build time is minimal.
We did some research as to why the kernel build was done like this in
Buildroot, and it's been like that since linux/linux.mk was added back
in 2010 by commit 487e21cff6 ("New,
simpler, infrastructure for building the Linux kernel").

Linux picks up the correct libraries.
