+rust: rustdoc reproducibility issue fix
+
+The 'codegen-units' option split the crate into multiple compilation units for parallel compilation. Currently, this split is causing the rustdoc to generate differnt binary between the builds.
+To fix this the codegen-units & the lto options are disabled.
+
+More info about options:
+https://doc.rust-lang.org/cargo/reference/profiles.html#codegen-units
