`debian-rules-uses-as-needed-linker-flag`

The debian/rules file for this package uses the -Wl,--as-needed linker flag.

The bullseye toolchain defaults to linking with --as-needed and therefore it should no longer be necessary to inject this into the build process.

However, it is not safe to make this change if the package will target the buster distribution such as via backports to the buster-bpo / stable-bpo distribution or, during the bookworm cycle itself, the oldstable-bpo distribution.
