But we still rely on Travis-CI (Ubuntu Bionic 18.04 LTS)
for non-x86 targets until we have figured out who is willing
to share/maintain such non-x86 native runners on Gitlab.
There:
$ clang --version
clang version 6.0.0-1ubuntu2 (tags/RELEASE_600/final)
If we don't use Travis-CI, then your patch is fine, but we
need a previous patch removing .travis.yml.
