--- Comment #4 from Jonas Hahnfeld <hahnjo at hahnjo.de> ---
Reverted in r337722. This basically meant that Linux systems without libatomic
couldn't use OpenMP anymore.

https://clang.llvm.org/docs/Toolchain.html#libatomic-gnu explains that Clang
expects the user to link -latomic. We should discuss if this default can be
changed while not regressing the current OpenMP support.
