From bc5c404e7415108f15a8cd5e8514a74b43a7755a Mon Sep 17 00:00:00 2001

Subject: [PATCH] Support debuginfo subpackages
We do this by filtering the debuginfo files generated by find-debuginfo.sh
with the files from the (sub)packages.
This commit is heavily based on a patch by Richard Biener.
(cherry picked from commit 980749fdce055254ca92ee7e2595b16750b699a2)
