@peti w.r.t.
Is there anything documenting why this is needed (ticket, commit, …)? I had a 8.6.2 in my own checkout and it built and worked fine without this patch. I'm sure it was initially added for a reason but I want to check if it's not just the case of some old workaround ending up being copied and pasted for every subsequent version.
