If two builds are sharing the same DL_DIR, and the uninative file is local to a layer. When the first build gets to uninative it creates the link local to itself, and subsequent users can use the same link. However if that first build then is deleted from the disk, the symlink is no longer valid (broken). We need to update the system to detect this case, and use the model implemented by the bitbke fetch2 code. Look for a broken link, remove it, then try to create the link and ignore an exception if it already exists (since we just unlinked any bad one).

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.
