I don't see the samples error. :(

I do get this, though:

  OBJCOPY arch/s390/boot/compressed/vmlinux.bin
  GZIP    arch/s390/boot/compressed/vmlinux.bin.gz
  AS      arch/s390/boot/compressed/head.o
  CC      arch/s390/boot/compressed/misc.o
  LD      arch/s390/boot/compressed/piggy.o
s390x-linux-gnu-ld: arch/s390/boot/compressed/vmlinux.bin.gz: not in ELF format

make[1]: *** [arch/s390/boot/compressed/vmlinux] Error 2

I'm using:
