After a first attempt to fix the test-suite failures, my first recommit caused the same failures again. I had updated CMakeList.txt files of tests that needed -fcommon, but it turns out that there are also Makefiles which are used by some bots, so I've updated these Makefiles now too. See the original commit message for more details on this change: 0a9fc9233e172601e26381810d093e02ef410f65
