Richard Purdie 055695994a oeqa/concurrencytest: Optimise for autobuilder/clobberdir
We're seeing huge delays on the autobuilder during oe-selftest builddir
deletion. For example there is a currently running selftest we could do
with the results from and its been going 13 hours, at least 8 of which
was in deletion of the builddirs.

There are a variety of ways we could solve this problem however the
autobuilder has a mechanism for deferred deletion, "clobberdir" which
it already uses for this kind of work.

Whilst in general hardcoding things like this is horrible, I believe
in this case the benefits (and resulting improvements on my sanity
if nothing else) mean this is a case where we should do it.

If/as/when someone can come up with a better solution that is fine
and this can be replaced.

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.
