Joshua Watt b2d55ec1eb bitbake: knotty: Update hash equivalence logging
Updates hash equivalence logging so that the interesting VERBOSE
messages are always logged to the consolelog file so that issues in
individual user builds can be diagnosed. The autobuilder logging config
then updates this so that they also are shown on stdout, since the
consolelog file is not capture there.

In order to facilitate this, 2 new logging handlers were added,
"BitBake.verbconsole" and "BitBake.verbconsolelog". Neither of these
handlers are attached to anything by default, but they will log any
messages that wouldn't otherwise be logged by the normal console or
consolelog handlers. Users can attach whatever loggers the desire to
this handler to get them to appear on the console or in the consolelog,
as demonstrated by the autobuilderlog.json file.

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.
