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")

These are all calling x86 entry code functions, so move them close
to other entry code.
Change lib-y to obj-y: there's no real difference between the two
as we don't really drop any of them during the linking stage, and
obj-y is the more common approach for core kernel object code.

Highmem was always buggy and experimental on UML(i386).
In times where 64 bit computers are default we can
remove that experimental code.

Now when the native kernel uses a single style of generated system
call table, follow suite for UML and implement the same style, all in
C. This requires __NR_syscall_max and NR_syscalls to be generated; on
native this is done in asm-headers.h but that file is common to all
UML architectures; therefore put it in user-headers.h instead which
already have accommodations for architecture-specific values.
