Using populate_sysroot for this data was a nice idea but flawed as it
doesn't work in multilib builds. Instead we can use PKGDATA_DIR since
this is consistent over multilib builds. It also turns out to be
slightly neater code too. Hopefully this resolves the problem once and
for all.

Perf.bb (among others) requires access to the kernel source, so have linux-dummy fake that as well. As before, perf will fail to build, but there are use cases where this patch is needed. For example a perf.bbappend that will always build it from the debian linux-tools tarball.
Using linux-dummy is still a bad, bad idea, but it shouldn't start breaking existing use cases.

[YOCTO #7230]
In certain system configurations TRANSLATED_TARGET_ARCH will not
expand in the right order for gcc-cross-candian-mips64n32 to be
generated properly.
This will cause SDKs to fail to generate properly.
Changing the global definition of TRANSLATED_TARGET_ARCH always
expands the ABIEXTENSION, which causes the OVERRIDES to pick it up
as well. This effectively defines a new class of overrides for the 'n32'.
The side effect is that we need to duplicate some mips64 overrides, and
redefine others that were previously 'n32' or 'mips64' exclusive to have
the correct semantics.

debug and logging will make kmod and its library bigger than expected
due many strings in the resulting binaries. While these are useful for
development, they are of no use for deployment.
With them enabled kmod is 154Kb, libkmod is 99Kb. Disabling reduces to
kmod 139Kb (10%) and libkmod 83Kb (19%) on i586 stripped.

With the rpm package backend enabled, running:
bitbake <image>
bitbake virtual/kernel -c clean
bitbake <image> -c rootfs -f
results in an image with incorrect kernel module dependency information.
The problem is that the System.map and kernel-abiversion files are needed
for depmod and after the recent kernel changes, these are no longer in
sstate.
Its reasonable to require the kernel to unpack/build if you're
about to build a module against it. It is not reasonable to require this
just to build a rootfs.
Therefore stash the needed files specifically for depmod.
Also fix some STAGING_KERNEL_DIR references which were incorrect, found
whilst sorting through his change.

Since virtual/kernel do_compile modifies ${B}, we need to wait for
do_compile to copy everything across in order to ensure a deterministic

Currently, we race against the build and can see .debug directories, and
the do_compile dependency we will always see them. Add .debug to the
find path pruning.

commit 3b3f7e785e279 [kernel: Rearrange for 1.8] began the process of
moving the kernel source and build artefacts out of sstate control and
into a shared location.
This changed triggered some workflow issues, as well as bugs related
to the kernel source containing build output, and hence being dirty and
breaking kernel rebuilds.
To solve these issues, and to make it clear that the kernel is not under
sstate control, we move the source and build outputs to:
work-shared/MACHINE/kernel-source
work-shared/MACHINE/kernel-build-artifacts
Where kernel-build-artifacts is the kernel build output and
kernel-source is kept "pristine". The build-artifacts contain everything
that is required to build external modules against the kernel source,
and includes the defconfig, the kernel-abiversion, System.map files and
output from "make scripts".
External module builds should either pass O= on the command line, or
set KBUILD_OUTPUT to point to the build-artifacts. module-base.bbclass
takes care of setting KBUILD_OUTPUT, so most existing external module
recipes are transparently adapted to the new source/build layout.
recipes that depend on the kernel source must have a depedency on the
do_shared_workdir task:
do_configure[depends] += "virtual/kernel:do_shared_workdir"
With this dependency added, the STAGING_KERNEL_DIR will be populated and
available to the rest of the build.

Make aarch aarch64 kernel depend on libgcc.
In arch/arm64/Makefile, it adds LIBGCC to libs-y:
LIBGCC := $(shell $(CC) $(KBUILD_CFLAGS) -print-libgcc-file-name)
libs-y += $(LIBGCC)
In file Makefile in top directory, libs-y is assigned to to var
KBUILD_VMLINUX_MAIN. It uses script link-vmlinux.sh to link vmlinux.o,
and when execute function vmlinux_link() in link-vmlinux.sh,
KBUILD_VMLINUX_MAIN is passed to ${LD}.
If build without libgcc, the value of LIBGCC is just libgcc.a without
parent directory. linux-yocto fails to build:
| LD vmlinux.o
| aarch64-poky-linux-ld.bfd: cannot find libgcc.a: No such file or directory

module-base.bbclass
do_install for kernel-devsrc can race against do_make_scripts from
module-base.bbclass. Since there is a lock there to guard against concurrency
already, we can just use it here to avoid a race.
Ultimately, this can all likely be much more streamlined but this resolves
the immediate build failures.

kernel-devsrc is responsible for creating and a packaging an environment
appropriate for kernel development (on or off target).
To create this support, we only need to copy/install the results of the
virtual/kernel providers build in the staging dir ... with some minor
manipulations to the source tree (.git removal and a clean up). This
produces a source tree that is capable of rebuilding the kernel on the
target.
Installing the kernel-devsrc package on a target (along with a
toolchain) is all that remains to be done.
$ cd /usr/src/kernel
$ make oldconfig
$ make -j2 bzImage

In 1.8 we want to streamline the kernel build process. Basically we
currently have multiple copies of the kernel source floating around
and the copying/compression/decompression is painful.
Lets assume we have a kernel source per machine since in most cases
this is true (and we have a sysroot per machine anyway). Basically,
instead of extracting a source into WORKDIR, then copying to a sysroot,
we now set S to point straight at STAGING_DIR_KERNEL.
Anything using kernel source can then just point at it and use:
do_configure[depends] += "virtual/kernel:do_patch"
to depend on the kernel source being present. Note this is different
behaviour to DEPENDS += "virtual/kernel" which equates to
do_configure[depends] += "virtual/kernel:do_populate_sysroot".
Once we do this, we no longer need the copy operation in
do_populate_sysroot, in fact there is nothing to do there (yay).
The remaining part of the challenge is to kill off the horrible
do_install. This patch splits it off to a different class, the idea here
is to have a separate recipe which depends on the virtual/kernel:do_patch
and just installs and packages the source needed to build modules on
target into a specific package.
Right now this code is proof of concept. It builds kernels and kernel
modules. perf blows up in do_package with issues on finding the kernel
version which can probably be fixed by adding back the right bit of do_install,
and adding a dependency of do_package[depends] += "virtual/kernel:do_install"
to perf. The whole thing needs a good write up, the corner cases testing
and probably a good dose of cleanup to the remaining code.
