Summary:
Some clang versions (< 6.0) do not inline the atomic builtin functions
leaving unresolved references to `__atomic_load_8` and so on (seems to
be mostly 64-bit atomics on 32-bit platforms).
I tried without success to use some cmake magic to detect when that
would be the case, and decided to fall back to unconditionally
linking libatomic.
