libatomic link instruction

println!("cargo:rustc-link-lib=dylib=atomic");

[messense]

Nothing we can do here, zig has some known issue for atomic, for example ziglang/zig#14889.

scratch that, it should be fixed in https://github.com/purpleprotocol/mimalloc_rust/blob/a9c410c248859d3f55fbb7d29a88f28cdf296f6b/libmimalloc-sys/build.rs#L58-L61 because armv7 and later does not require libatomic.
