-Wunused-result warning in test_logthrottling.cc was causing error when trying to build MaxScale from source. This warning can be silenced with by putting the function triggering the warning in if-clause.
This rules out external influence as a reason for the test failure.
Now, given a concept xyz, * the main test file is called test_xyz.cc * the executable is called test_xyz, and * the ctest test is called text_xyz.
