Fix linkage error when CONFIG_BINFMT_ELF is selected but CONFIG_COREDUMP is not:
ia64-linux-ld: arch/ia64/kernel/elfcore.o: in function `elf_core_write_extra_phdrs': elfcore.c:(.text+0x172): undefined reference to `dump_emit' ia64-linux-ld: arch/ia64/kernel/elfcore.o: in function `elf_core_write_extra_data': elfcore.c:(.text+0x2b2): undefined reference to `dump_emit'
