It's a bit more complicated than that:

 - If it uses atomic built-ins, one needs to "depends on

 - It can also use sync builtins.

So I've fixed that up, and applied your patch with the following

     - add the dependency on sync or atomic builtins in Config.in
     - use -DCMAKE_EXE_LINKER_FLAGS instead of
       -DCMAKE_C_STANDARD_LIBRARIES, to be consistent with what we do in
       some other cmake-based packages
     - tweak commit log]
