The absence of symbol sizes broke build comparison that looks for and ignores snapshots. Add symbol types for good measure to match the compiler behavior. Consider unknown operating systems to use as(1)-style assembly, which is generally true. If an unknown operating system uses another syntax, the generated files will fail to assemble and the porter should soon find this script and add support for their operating system.
