Hi Bruce,

Without this patch it happens that do_populate_recipe_sysroot is
called just before do_compile (on multi core build machines).
This is way too late as the .config generated in
do_kernel_configme() is already broken.
The problem is that do_kernel_configme() calls native's
merge_config.sh script which may call bison and arm-linux-*-gcc to
compile kconfig infrastructure to create base .config
(scripts/kconfig/conf --allnoconfig Kconfig.)
It turns out that we only got above binaries after
do_prepare_recipe_sysroot() is called.
If those binaries are not available, the merge_config.sh do not
generate base .config and without any error produces
malfunctioned .config. The build process continues and as a result
broken kernel is compiled.
To reproduce:
bitbake -c cleansstate virtual/kernel
bitbake -c kernel_metadata -v virtual/kernel
bitbake -c do_kernel_configme -v virtual/kernel
(one shall see broken .config in ${B}/.config)
bitbake -c do_populate_sysroot -v virtual/kernel
bitbake -c do_compile -v virtual/kernel

On a closer look .. what branch is this from ? We already have a
change that triggered breakage on 4.17+ that should fix this.
i.e. commit ff1bdd75d50f0ebac3d599e461685ace29559a82 in oe-core, adds:

Which I don't see in the context of your patch.
I do use poky as in the commit message.
Yes, I checked that .. but that isn't a useful part of a patch
to oe-core.
The kernel-yocto bbclass in that context is not the one in master, and
if I run a --contains on that commit ID, I don't get an active
branch.
So the patch as it stands, cannot be applied to master (and I
also checked master-next in case something snuck in that I
missed) of oe-core or poky, so there's no way to work with it.

Regarding the kernel - I do have my own recipe;
inherit kernel
require
recipes-kernel/linux/linux-yocto.inc
And then I do have:
COMPATIBLE_MACHINE_display5 = "display5"
KBUILD_DEFCONFIG_pn-linux-yocto-custom_display5 =
"imx6q_display5_defconfig"
As the board is in mainline I just point to Linus tree.
