Fix the linker so that it will not silently generate ELF binaries with invalid program headers. Fix readelf to report such invalid binaries.
PR ld/20815
bfd * elf.c (elf_modify_segment_map): Allow empty LOAD segments if
they contain the program headers.
(_bfd_elf_map_sections_to_segments): If the linker created the
PHDR segment then always attempt to include it in a LOAD segment.
(assign_file_positions_for_non_load_sections): Allow LOAD segments
to overlap PHDR segments.
(phdr_sorter): New function. Sorts program headers.
(assign_file_positions_except_relocs): Sort the program headers
before writing them out. Issue an error if the PHDR segment is
not covered by a LOAD segment, unless the backend allows it.
* elf-bfd.h (struct elf_backend_data): Add
elf_backend_allow_non_load_phdr.
* elfxx-target.h (elf_backend_allow_non_load_phdr): Provide
default definition that returns FALSE.
(elfNN_bed): Initialise the elf_backend_allow_non_load_phdr
field.
* elf64-hppa.c (elf64_hppa_allow_non_load_phdr): New function.
Returns TRUE.
(elf_backend_allow_non_load_phdr): Define.
* elf-m10300.c (_bfd_mn10300_elf_size_dynamic_sections): Do not
place the interpreter string into the .interp section if the
nointerp flag is set in the link info structure.
* elf32-arc.c (elf_arc_size_dynamic_sections): Likewise.
* elf32-score7.c (score_elf_final_link_relocate): Allow for the
_gp symbol not being part of the output.
binutils* readelf.c (process_program_headers): Check PT_LOAD and PT_PHDR
segments for validity.
ld * ld.texinfo: Note that PT_TLS can be used as a segment type.
