The `can_compile` utility writes its temporary output file to the system's global temporary directory. This can clutter the host system with build artifacts. By using Cargo's `OUT_DIR`, the temporary file is written to a directory specific to the build, ensuring that build artifacts are contained within the project's build output and do not mess up the host system. Follow-up to bytecodealliance#1497.
