s390: add relocs tool

This 'relocs' tool is copied from the x86 version, ported for s390, and
greatly simplified to remove unnecessary features.

It reads vmlinux and outputs assembly to create a .vmlinux.relocs_64
section which contains the offsets of all R_390_64 relocations which
apply to allocatable sections.
