Currently, if files move between recipes, do_prepare_sysroot can fail with a message like Exception: FileExistsError: [Errno 17] File exists: 'TMPDIR/sysroots-components/core2-64/libx11/usr/include/X11/extensions/XKBgeom.h' -> 'TMPDIR/work/core2-64-poky-linux/gtk+3/3.24.8-r0/recipe-sysroot/usr/include/X11/extensions/XKBgeom.h' This is because files are removed and then added per package. What needs to happen is all removes need to be processed, then all additions. This patch changes the code to process in two phases, removals first, then additions, which avoids the problem.

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.
