[PATCH] D56553: [WebAssembly] Change the default lib path for wasm32 to be lib32

This changes the default lib path from plain "lib" to "lib32", and anticipates a future "lib64". While not every architecture uses this naming scheme, "lib32"/"lib64" is consistent with the naming of "wasm32"/"wasm64".
