[test-suite] switch Clang driver to default to -fno-common

I've tried recommiting the Clang patch to switch to -fno-common, but
again some of the build bots turned red running the test-suite. After my
first commit, I added -fcommon to CMakeLists.txt for some benchmarks
that need this, see my previous test-suite commit. After the recommit,
and the same tests failing again on some bots, I realised that some bots
use Make, so this adds -fcommon to also their Makefiles.
