Add option 'deterministic' for reproducible builds
Add the option 'deterministic' to make it easier to achieve reproducible builds. This option omits the {options,...} and {source,...} tuples in M:module_info(compile), because those options may contain absolute paths. The author of ERL-310 suggested that only compiler options that may contain absolute paths (such as {i,...}) should be excluded. But I find it confusing to keep only some options. Alternatives considered: Always omitting this information. Since this information has been available for a long time, that would probably break some workflows. As an example that some people care about {source,...}, 2d785c07fbf9 made it possible to give a compiler option to set {source,...}. ERL-310
