Cryptsetup and libvirt are new.
OpenSSL was moved with the rest.
The dynamic libaries cryptsetup and libvirt also ship a file called closure.tar,
that contains the transitive closure for all of their dependencies.
This tar file can be used as a container image layer or added to a bootable OS image
to provide the runtime dependencies required for dynamic linking.
Additionally, they ship a `rpath` file. This can be used together with patchelf to
fix the RPATH of binaries produced by Bazel.
