This change has recently been uploaded to DELAYED/15 by Mattia from the
Reproducible Builds team after I requested that; in addition I'm providing the
same change as a merge request on Salsa (adding this as the forwarded-to URL
for reference, although in this case the change itself is a backport from
upstream).
