[RESEND PATCH] ia64: Fix build error with !COREDUMP

[RESEND PATCH] ia64: Fix build error with !COREDUMP

[Krzysztof Kozlowski]

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'

Cc: <stable@vger.kernel.org>
Fixes: 1fcccbac89f5 ("elf coredump: replace ELF_CORE_EXTRA_* macros by functions")
Reported-by: kernel test robot <lkp@intel.com>
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

---

This is similar fix to commit 42d91f612c87 ("um: Fix build error and
kconfig for i386") although I put different fixes tag - the commit which
introduced this part of code.
