the current status is that rustc has flags to remap the file paths, which I think makes the situation with rust the same as the situation with every other build system. pretty much every build system will by default leak paths and times and whatnot from the builder, and need to be configured to not do that. AFAICT, the open issues are that some people want that to be the default and a few people are upset that changing the default requires an RFC.
