>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").

Xenomai has two mutually exclusive cores:
- Cobalt: dual-kernel approach: patched kernel + userland
- Mercury: only userland
In the Cobalt core, not all architectures are supported. This is the source
of the existing ARCH_SUPPORTS variable.
In the Mercury core, there is no imposed architecture restriction.
Rename the XENOMAI_ARCH_SUPPORTS flag to XENOMAI_COBALT_ARCH_SUPPORTS and
move its check from the Xenomai package to the Cobalt core.
Nevertheless, even for Mercury, there are some restrictions:
- pthread_atfork is used, which requires an MMU
- sync functions like __sync_sub_and_fetch and __sync_add_and_fetch are
expected.
As the corresponding 'linux extension' selects Xenomai, we add the
MMU and sync dependencies there too. They may or may not already be covered
by XENOMAI_COBALT_ARCH_SUPPORTS flag.

linux is a bit different than other kconfig-package, because it has
"toolchain" in KCONFIG_DEPENDENCIES. Thanks to this, host-ccache *is*
ready by the time kconfig invocations are made, so we could use
$(HOSTCC) as the host compiler for kconfig related operations.
However, for consistency with other kconfig-package packages, we chose
to use $(HOSTCC_NOCCACHE) as well.
We cannot rely on the default value of HOSTCC passed by the
kconfig-package infrastructure, because $(LINUX_MAKE_FLAGS) also
contains a HOSTCC definition that would override the one passed by the
kconfig-package infrastructure.

When using an initramfs, on the first-pass build, we create a dummy cpio
so that the build succeeeds. The real cpio will come later, and we'll do
a second-pass build to use the actual cpio.
However, when we touch that dummy cpio, the images/ directory may not
yet exist, since commit d0f4f95e39 (Makefile: rework main directory
creation logic) removed its creation at the begining of the build, to
only at the moment we need it, i.e. during the *_INSTALL_IMAGES_CMDS
steps.
However, the linux build is not a _INSTALL_IMAGES_CMDS step, so there is
no guarantee that images/ already exist at that time.
Fix that by explicitly creating images/ before touching the dummy cpio.
