After taking a deeper look, this ended up being a pretty obvious mistake on my part. Please try wine-staging 6.23 (should be fixed by 24753f8756ff982ee20cbb98bda79b15c8c3d57d).
I don't know what exactly the problem was, but I confirm that the initially discribed problem (with relative symlinks) is gone with 24753f8756ff982ee20cbb98bda79b15c8c3d57d (I did two builds - with this commit and one previous).
Now this topic can be closed. Thanks you, Erich E. Hoover.
