IANA atomics expert, but GCC documentation describes the __sync_*[0] 
built-in functions as "legacy", and I hypothesize that the __atomic_*[1] 
built-in functions are more widely available. The attached patch let me 
build mapsembler2 on powerpc, although probably all the other __sync_* 
calls should be replaced by __atomic_*. I didn't test if the package 
still works after these changes.
