 > expression to replace the leading ./ with the package name and version.

 > This causes issues when a package contains symlinks that points to
 > ./something, as the leading './' is also replaced.

 > Fix that by using the 'S' transformation scope flag, as described in the
 > tar manual:
 >   https://www.gnu.org/software/tar/manual/html_node/transform.html#transform

 >   In addition, several transformation scope flags are supported, that
 >   control to what files transformations apply. These are:

 >   ?r? Apply transformation to regular archive members.
 >   ?R? Do not apply transformation to regular archive members.
 >   ?s? Apply transformation to symbolic link targets.
 >   ?S? Do not apply transformation to symbolic link targets.
 >   ?h? Apply transformation to hard link targets.
 >   ?H? Do not apply transformation to hard link targets.

 >   Default is ?rsh? [...].

 > Fixes: #13616
