Subject: [PATCH] um: Fix build error and kconfig for i386

Fix build error by selecting COREDUMP when X86_32 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':
