Peter,
You will want to get that one for 2021.02, and also 2020.11 and 2020.02
if they are a still alive.
You may want to complement the commit log with the scriptlet I added in
c9f27fdc1b (and adding opkg-utils to the list of host-only packages):
I've tested locally that our current hashes are still valid.

> fix tarball generation with symlinks pointing to ./something
>
> When a --transform expression is provided, it is by default also applied
> to the target of a symlink.
>
> When we create tarballs (from git or svn checkouts), we use a --transform
> 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
