[RFA]: minor change to gdb_test dejagnu proc

[Michael Snyder <msnyder at cygnus dot com>]

Fernando, 

This is the change that you commented on earlier.  It does NOT
cause any new tests to fail -- it only adds more info about
WHY the test failed.  I happened to notice that gdb_test would
do this if a test failed due to ABNORMAL termination -- and
I thought it would be helpful if it also identified failures
due to NORMAL termination.

        * lib/gdb.exp (gdb_test): Add case to identify failures due to
        "program exited normally".  No new fails -- just more info.
