* internal.h (ELF_IS_SECTION_IN_SEGMENT): Check both file offset
	and vma for appropriate sections.
bfd/
	* elf.c (assign_file_positions_for_load_sections): Set sh_offset
	here.  Set sh_type to SHT_NOBITS if we won't be allocating
	file space.  Don't bump p_memsz for non-alloc sections.  Adjust
	section-in-segment check.
	(assign_file_positions_for_non_load_sections): Don't set sh_offset
	here for sections that have already been handled above.
