Richard Purdie 9254d537aa bitbake: runqueue: Small performance optimisation
A minor performance optmisation to keep lists smaller when running large
builds. We can do this since once a task has been built, we don't need
to worry about it. This improves a major bottleneck that shows up on
performance profile charts in dryruns.

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.
