    PR31667, objcopy/strip corrupts solaris binaries
    
    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.
