try_mirror_url() creates a symlink named as the original file to make everything look like files specified in SRC_URI were downloaded from their original location. The link is however created as an absolute reference, this makes DL_DIR non-relocatable. This also causes issues with the Isar project since it bind mounts DL_DIR to /downloads to perform some of its build tasks in a chrooted environment (rendering all symbolic links from DL_DIR invalid). Modify ensure_symlink() to take an optional "relative" argument and have that function use os.path.relpath() to produce a relative symlink.

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.
