Hi,
libatomic detection is currently broken in configure.ac; it will
define -latomic even in case where it wouldn't be required (e.g.
because it's already provided by the compiler).
The attached patch fixes the broken case. Unfortunately I don't know a
system where this library is required, I'm convinced there's room for
further simplification.
