PR binutils/12467
* readelf.c (process_program_headers): Issue a warning if there are no program headers but the file header has a non-zero program header offset. (process_section_headers): Issue a warning if there are no section headers but the file header has a non-zero section header offset. (process_section_groups): Reword the no section message so that it can be distinguished from the one issued by process_section_headers. * elf.c (assign_file_positions_for_load_sections): Set the program header offset and entry size to zero if there are no program headers.
