Fix build error by generating elfcore.o only when ELF_CORE (depending on
COREDUMP) is selected:
arch/x86/um/built-in.o: In function `elf_core_write_extra_phdrs':
(.text+0x3e62): undefined reference to `dump_emit'
arch/x86/um/built-in.o: In function `elf_core_write_extra_data':
(.text+0x3eef): undefined reference to `dump_emit'
Fixes: 5d2acfc7b9 ("kconfig: make allnoconfig disable options behind EMBEDDED and EXPERT")
