1a9ccd70f9 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.

	place the interpreter string into the .interp section if the
	nointerp flag is set in the link info structure.
