This patch fixes a warning that can be reproduced with gcc-8.5 on RHEL8
(gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-28)).

This should fix issue #3303.

Must be backported everywhere 917e82f283 ("MINOR: debug: copy debug
symbols from /usr/lib/debug when present") was backported, which is
to branch 3.2 for now.
