	* elf.c (assign_file_positions_for_load_sections): Adjust p_vaddr
	by p_vaddr_offset.  Copy alignment & use if it is valid.
	(rewrite_elf_program_headers): Cope with leading padding in a
	segment that does not contain file or program headers.
	(copy_elf_program_header): Likewise.

	include/elf/
	* internal.h (struct elf_segment_map): Add p_vaddr_offset field.
