    - Add llvm-lifetime-for-rust.patch to have Rust memory management
      functions considered as lifetime markers. This should aid dead
      store elimination to dynamically allocated memory in Rust code.
    - Don't declare python3-clang as noarch: Python packages are
      installed into %{_libdir}.
    - Use black RPM macro magic to deduplicate binary lists. This
      should have no effect on the generated RPM but shaves ~400 lines
      off the specfile and hopefully makes future maintenance easier.
