Richard Purdie ff872fdda5 bitbake: runqueue: Change task migration behaviour for rerunning setscene tasks
Currently runqueue will rerun setscene tasks multiple times as hashes
change. This has caused numerous problems since a setscene task may
become "unavailable" for some future signature combination and the code
then can't easily "unskip" tasks its already passed into the execution
queue.

At least for now, only run setscene once and assume they're equivalent
at that point. In practise that has been much more stable in testing.

Tweak the test to match the change in behaviour.

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.
