This reverts commit 2e7f3b2b9318d1e5395ad58131eafb873f614326. It was breaking quite common use case that the dtb files are in some subdirectory and then kernel build fails to build them. As reported by khem: http://lists.openembedded.org/pipermail/openembedded-core/2018-July/152578.html me: http://lists.openembedded.org/pipermail/openembedded-core/2018-July/152579.html on raspberrypi3 build: make[3]: *** No rule to make target 'arch/arm/boot/dts/dwc2.dtbo'.

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.
