I'm trying to follow your reproducer and installed binutils-s390x-linux-gnu.

However: 

make CC=clang HOSTCC=clang W=1 ARCH=s390 arch/s390/ 
  SYNC    include/config/auto.conf.cmd
  CALL    scripts/checksyscalls.sh
  VDSO    arch/s390/kernel/vdso64/vdso64.so.dbg
ld: unrecognised emulation mode: elf64_s390
Supported emulations: elf_x86_64 elf32_x86_64 elf_i386 elf_iamcu i386pep i386pe
make[2]: *** [arch/s390/kernel/vdso64/Makefile:53: arch/s390/kernel/vdso64/vdso64.so.dbg] Error 1
make[1]: *** [arch/s390/Makefile:150: vdso_prepare] Error 2
make: *** [Makefile:248: __sub-make] Error 2

My linker can't do s390. So I need something else which your system has.
