	PR binutils/5449
	* elf.c (rewrite_elf_program_header): Don't adjust p_paddr if
	p_paddr is set to 0.
	(copy_private_bfd_data): Call rewrite_elf_program_header if
	p_paddr is set to 0.

	* elfcode.h (elf_swap_phdr_out): Set p_paddr to 0 if needed.

	* elfxx-ia64.c (ELF_MAXPAGESIZE): Don't redefine it for HPUX.
