* elf.c (assign_file_positions_for_load_sections): Remove assertions that only PT_LOAD headers include file header and section headers. (assign_file_positions_for_non_load_sections): Similarly don't assert PT_GNU_RELRO header does not include file and section headers. Compare first section vma rather than PT_LOAD p_vaddr against relro_start when looking for PT_LOAD covering PT_GNU_RELRO. Replace abort with assertion.
