Richard Purdie e18bb3f56b bitbake: runqueue: Fix hash equivalence duplicate tasks running
The key problem is that currently running setscene tasks are not
accounted for when processing task migrations. This means can allow
two of the same task to execute at the same time with unpredictable
effects.

This change allows us to stop doing that and refactor the code slightly
to make it clearer that these conditions don't arrive even with
deferred tasks.

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.
