doc: keep just one copy of a coredump analysis
Keeping two copies of the files means, one would be out-of-date soon, and users would always be confused about which one is the source of truth. Updates: bz#1193929 Change-Id: I568149732fdb9d282ccd583640eee9b9056963fd Signed-off-by: Amar Tumballi <amarts@redhat.com>

-4) Now, run the following command on the core:
-~~~
-gdb -ex 'set sysroot ./' -ex 'core-file ./build/install/cores/core.xxx' <target, say ./build/install/sbin/glusterd>
-In this case,
-gdb -ex 'set sysroot ./' -ex 'core-file ./build/install/cores/core.9341' ./build/install/sbin/glusterfsd

-5) You can cross check if all shared libraries are available and loaded by using 'info sharedlibrary' command from
-inside gdb.
-6) Once verified, usual gdb commands based on requirement can be used to debug the core.
