Subject[PATCH] Use ELF_CORE_EFLAGS for kcore ELF header flags.
ELF_CORE_EFLAGS is already used by the binfmt_elf coredumper to set correct 
arch specific ELF header flags on coredumps. Use it for kcore aswell.
This corrects kcore files for the CRIS arch and I beleive it corrects
ordinary coredumps for the H8/300.
