So in build directory:
lrwxrwxrwx 1 tv users    39 Gwe  15 12:04
./BUILD/LVM2.2.03.10/shared/daemons/dmeventd/plugins/snapshot/libdevmapper-event-lvm2snapshot.so
-> libdevmapper-event-lvm2snapshot.so.2.03
-rwxr-xr-x 1 tv users 34800 Gwe  15 12:04
./BUILD/LVM2.2.03.10/shared/daemons/dmeventd/plugins/snapshot/libdevmapper-event-lvm2snapshot.so.2.03

In BUILDROOT:

 -r-xr-xr-x 1 tv users 34792 Sep 15 12:52
/home/tv/mga/pkgs/UTILS/lvm2/BUILDROOT/lvm2-2.03.10-3.mga8.x86_64/usr/lib64/device-mapper/libdevmapper-event-lvm2snapshot.so

Installed system:
-rw-r--r-- 1 root root 14624 Gwe  10 11:42
/usr/lib64/device-mapper/libdevmapper-event-lvm2snapshot.so
(because of "%defattr(644,root,root,755)")

-r-xr-xr-x 1 root root 14624 Gwe  15 12:58
/usr/lib64/device-mapper/libdevmapper-event-lvm2snapshot.so*
(w/o "%defattr…")

So it looks like the culprit is the package's BS:
/usr/bin/install -p -m 555  -D libdevmapper-event-lvm2snapshot.so
/home/tv/mga/pkgs/UTILS/lvm2/BUILDROOT/lvm2-2.03.10-3.1.mga8.x86_64//usr/lib64/device-mapper/libdevmapper-event-lvm2snapshot.so

The question is why does it show now?
Was some output redirected to /dev/null previously?
Should either find-debuginfo.sh or objcopy workaround perms (by using a
temp file with proper perms, then move/overwite & re-set the original
perms?)
