- Make the libevent install patch take CMAKE_INSTALL_LIBDIR instead of
hardcoding lib/x86_64-linux-gnu, and rename it to
libevent-libdir-install.patch.
- Replace every hardcoded x86_64-linux-gnu in the debian13 Dockerfile with
$(gcc -dumpmachine).
- Download the Rust tarball for `uname -m` and expose it to the Dockerfiles
as the architecture-neutral rust-1.99.1.tar.xz (a hard link refreshed on
every run), because podman cannot expand ARG in a --mount source.
