Mike Looijmans 2fcbd0f115 license_image.bbclass: Don't attempt to symlink to the same file
Sometimes (that is, in all my builds) the lic_manifest_dir and
lic_manifest_symlink_dir end up pointing to the same file, resulting
in an error like this:
  Exception: FileExistsError: [Errno 17] File exists: '/.../tmp-glibc/deploy/licenses/my-image-tdkz15' -> '/.../tmp-glibc/deploy/licenses/my-image-tdkz15'

First check to see if this is the case before attempting to create
the link.

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.
