useful in .config (and also include directory isn't created):

kernel with default defconfig, which even builds OK for qemux86-64
but on qemux86 I've noticed this issue, because incorrectly
configured kernel build fails with:

]because merge_config.sh is redirected to work-shared/qemux86/kernel-source/.kernel-meta/cfg/merge_config_build.log
and bbfatal_log called in do_kernel_configme only when merge_config.sh fails which it should in this case
but doesn't.
The merge_config_build.log shows 5.4 specific error:

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
