Richard Purdie 587a5de397 oeqa/selftest: recipetool/devtool: Avoid load_plugin test race
This bug has plagued the autobuilder for a couple of years and we've
struggled to reproduce/debug it.

The problem is the "lib" directory in meta-poky used during the load_plugin
tests for recipetool and devtool can race and one can delete the files
from the other leading to test failures.

Deleting the lib directory only if empty will avoid this.

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.
