As a follow up to the changes to ensure that KBUILD_DEFCONFIG will always get its defconfig into the processing, we also should ensure that we don't get both a KBUILD_DEFCONFIG and a SRC_URI defconfig in the configuration queue. If both are in the configuration queue, we end up with competing values and a potentially long running check of 5000+ options x 2 against the final .config. By removing the defconfig found from the SRC_URI when one is found via KBUILD_DEFCONFIG, we ensure that only one will be processed.

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.
