Alexander Kanavin b40f78a5c7 oeqa: tear down oeqa decorators if one of them raises an exception in setup
Some of the decorators need proper cleanup, such as OETimeout
which sets a signal handler that needs to be cleared via teardown.
If this is not done then the signal gets called later with unpredictable effects.

This can be seen if there's a test that is skipped via a decorator and sets a timeout
at the same time: the timeout isn't cleared, and is invoked later in a
completely unrelated context. The test case for this is added in the
next commit.

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.
