We simply follow the OpenCV "Template Matching with Multiple Objects"
tutorial, replacing Lionel Messi by Tux:
https://docs.opencv.org/4.2.0/d4/dc6/tutorial_py_template_matching.html
When OpenCV and NumPy are installed, this test can be run using:
$ avocado --show=app,framebuffer \
run -t cpu:i6400 \
tests/acceptance/machine_mips_malta.py

If the AVOCADO_CV2_SCREENDUMP_PNG_PATH environment variable is set, the
test will save the screenshot with matched squares to it.
Test inspired by the following post:
https://www.mips.com/blog/how-to-run-smp-linux-in-qemu-on-a-mips64-release-6-cpu/
Kernel built with the following Docker file:
https://github.com/philmd/qemu-testing-blob/blob/malta_i6400/mips/malta/mips64el/Dockerfile
