Some more context :

It has been fixed upstream in the 1.41 by adding this same flag in their build systems:

Since the problem has been fixed upstream, I'm not sure the Salsa MR will make it into Debian, as the maintainer might simply want to upload a new upstream version.

So I'll simply backport the upstream fix in Ubuntu. I think this will make it easier for a future contributor to identify that the fix can be safely drop in future syncs.
