BUILD: atomics: fix build issue on non-x86/non-arm systems

Browse Source 
Commit f435a2e518 ("CLEANUP: atomics: also replace __sync_synchronize()
with __atomic_thread_fence()") replaced the builtins used for barriers,
but the different API required an argument while the macros didn't specify
any, resulting in double parenthesis that were causing obscure build errors
such as "called object type 'void' is not a function or function pointer".
Let's just specify the args for the macro. No backport is needed.
