Using want_p_paddr_set_to_zero in commit 45d92439aebd was wrong. Even
solaris targets don't have want_p_paddr_set_to_zero, but we should
handle them at least somewhat reasonably.
PR 31667
* elf.c (IS_SECTION_IN_INPUT_SEGMENT): Remove bed arg, add
paddr_valid. Don't use bed->want_p_paddr_set_to_zero.
(INCLUDE_SECTION_IN_SEGMENT): Likewise.
(rewrite_elf_program_header): Adjust to suit.
