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.
