Richard Purdie fece8f4737 bitbake: runqueue: Optimise holdoff task handling
We don't need to process the holdoff task list until we're executing tasks
which saves some data manipulation, at the cost of some data structures
not being correct at all times. This saves significant amounts of time
in various profile charts of larger builds.

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.
