`__atomic_is_lock_free` undefined on clang

out/Release/obj.target/libnode/src/node.o: In function `node::RegisterSignalHandler(int, void (*)(int, siginfo_t*, void*), bool)':
node.cc:(.text+0x17b4): undefined reference to `__atomic_is_lock_free'

i'm on debian+wsl

update: adding -latomic fixes this, but i'm not sure where to put that within our build tooling.
