Commit 9eea43f9 authored by Moritz Angermann's avatar Moritz Angermann Committed by Ben Gamari

[linker] Adds elf_compat.h, util.h, elf_util.h

Further cleanup of the linker, we'll add elf_compat.h for a more
complete set of relocations.

Also Util.h has been added as suggested in the code already.

Depends on D3444, D3445
