This happens because Rust's own libcompiler_builtins provides atomic builtins like __sync_synchronize despite the fact that gcc already provides these builtins itself. The builtins provided by libcompiler_builtins should therefore be disabled.
I could not find where those are defined, but I could only find a reference to them: https://github.com/rust-lang/rust/blob/master/src/librustc_back/target/armv5te_unknown_linux_gnueabi.rs#L30
