doc/rel_notes: add note on libarchive dependencies
Checks
Commit Message
Since DPDK now registers an explicit dependency on libarchive, rather
than just putting -larchive in link args, we need to add a documentation
note about potential missing dependencies when static linking.

+* **Extra dependencies when linking against libarchive**
+
+ When the libarchive development package is present on the system,

+ However, on a number of Linux distributions, including, for example, Fedora and Ubuntu,
+ installing the libarchive dev package does not cause all required dependencies for static linking to be automatically installed too.
+ These additional dev packages, such as ``liblz4-dev`` and ``libacl1-dev`` on Ubuntu,
+ will need to be installed manually (if not already present)
+ to prevent errors with linking against DPDK static libraries.
