Richard Purdie c404b88959 reproducible: Allow configuration of saved debug output
If OEQA_DEBUGGING_SAVED_OUTPUT is set in the environment, use this location
to store reproducibile build failure output. This aids debugging on the
YP autobuilder in particular.

Use a date in the directory name to make it easier to find failure output.

Also clean up empty directories as they're unnecessary distracting noise.

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.
