Summary: wasm-ld requires --shared-memory to be passed when the atomics feature is enabled because historically atomic operations were only valid with shared memories. This change relaxes that requirement for when building relocatable objects because their memories are not meaningful. This technically maintains the validity of object files because the threads spec now allows atomic operations with unshared memories, although we don't support that elsewhere in the tools yet. This fixes and Emscripten build issue reported at https://bugs.chromium.org/p/webp/issues/detail?id=463.
