Now I think you mean that you want to just find /usr/bin/md5sum without ever
using /usr/lib/debug/usr/bin/md5sum.debug, right?

Then you can create your local build-id -> filename database specific to your
machine in some /var/lib/build-id/ .  Such database has nothing to do with the
core file itself.  Core file can be easily transferred to other hosts as it is
machine independent.  Core file is dependent only on the specific binaries
_content_ (not _names_) which is uniquely identified by their build-id.

/var/lib/build-id/ can be created/updated either during 'rpm -i' time or from
'/proc/sys/kernel/core_pattern' hook or via some inotify daemon watching /bin,
/usr/bin and other directories updates etc. etc.
