[PULL 01/22] tests/avocado: Add a test for a little-endian microblaze machine

["Alex Bennée" <alex.bennee@linaro.org>]

From: Thomas Huth <thuth@redhat.com>

We've already got a test for a big endian microblaze machine, but so
far we lack one for a little endian machine. Now that the QEMU advent
calendar featured such an image, we can test the little endian mode,
too.
