objcopy/strip ELF program header p_vaddr confusion

Browse Source 
copy_elf_program_header has logic to reject non-alloc sections when
calculating p_vaddr offset for padding, but blithely assumed the
first section in a segment was allocated.

	PR 16690
	* elf.c (copy_elf_program_header): Ignore first section lma if
	non-alloc.
