do_package has PKGDESTWORK as a cleandir and do_packagedata has it as an sstate-input dir. This means do_package wipes out the directory at both do_package and do_package_setscene. do_package_setscene and do_packagedata_setscene can run in parallel when installing from sstate which means they can wipe out parts of each other leading to interesting build failures. We therefore have to add in a hardlink copy so that the directories can work independently of each other.

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.
