This is a performance sensitive piece of code and the shear number of recursive loops is causing a significant and unscalable performance pain point. This change moves to a two step approach, firstly generating a list of recursive dependencies for any task, then applying this to the recursive tasks, iterating over things until no further dependencies are added. It was noticed an optimisation is possible and the list of recursive tasks need not contain the taskname, only the base task id. This allows a significant performance improvement and limits the size of the resursive task lists, improving speed.

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.
