We depend on GNU-specific du switch `--apparent-size`. Busybox has this implemented, but as `-b` instead. Another part of the build system uses `cp --preserve=timestamps`. This can be replaced by `rsync -t`, and rsync is already used through the file. Thanks to those changes, Serenity can be built on a Busybox system, without GNU coreutils.
