The libelf implementation from elftoolchain has a safety check in gelf_update_rel[a] to check that the data corresponds to a section that has type SHT_REL[A] [0]. If the relocation is updated before the section header is updated with the proper type, this check fails. To fix this, update the section header first, before the relocations. Previously, the section size was calculated in elf_rebuild_reloc_section by counting the number of entries in the reloc_list. However, we now need the size during elf_write so instead keep a running total and add to it for every new relocation.
