I can see why you're doing that, but I'm not really convinced it helps
the package.  Particularly, we're now even adding a labeled input,
which makes for a cursed situation where all but one inputs are
unlabeled¹.

IMHO, G-Expressions in phases serve in part to facilitate uses like
this.  They may not be nice, but those are upstream conditions we have
to cope with.  I'd rather do a proper unbundling of libgd.

Another "proper" solution could be as easy as using an unlabeled origin
and search-input-file.  However, this doesn't really work all that well
if you have to unpack the entire origin, hence what I've done here for
gnome-recipes.

Cheers

¹ Let's not even mention the necessity of 1/6 to enable that.  Back in
the day, there was a decision against giving origins labels because it
would add to the further propagation of label use throughout Guix,
while we want to drop them.
