From: Jan Blunck <jblunck@suse.de>
Subject: Dump elf headers to core per default

This patch changes the default of /proc/self/coredump_filter to write the elf
header of shared objects and the executable itself to the core file. This
change is necessary to read the build-ids generated by GCC from the produced
core files. These core files might not be readable by anncient versions of
GDB.
