[Crash-utility] crash version 4.0-2.15 is available

- Applied Kurt Rader's (kdrader(a)us.ibm.com) patch for SUSE SLES 9 "bigsmp" kernel LKCD dumpfiles, to fix "conflicting page" abort caused by a dumpfile header that is larger than the formerly hard-wired header size. - Fix for ppc64-only segmentation violation when running "bt" on the panic task when run against a dumpfile created by the diskdump facility's new compressed format.
