53e436d665
Fix renaming directory project using build scripts with cross-compiling. The rename-protection introduced in #4818 checks for paths with a prefix of `/…/target/debug`, but this does not work for paths used during cross-compiling. This change checks for paths with the full `OUT_DIR` prefix, and the `build/PKG/root-output` file now includes that full `OUT_DIR` instead of `/…/target/debug`. This also includes a few other changes: - Support fixing KIND=PATH style paths. - Support fixing paths in metadata (like `cargo:root=…` or `cargo:include=…` which are common). - Adds a "version" value to the metadata hash to ensure that cargo doesn't get confused with the new `root-output` file format. Fixes #6177
