    RISC-V: Fix ld relax failure with calls and align directives.

    Make _bfd_riscv_relax_call handle section alignment padding same as
    the _bfd_riscv_relax_lui and _bfd_riscv_relax_pc functions already
    do.  Use the max section alignment if section boundaries are crossed,
    otherwise the alignment of the containing section.

        PR 25181
        * elfnn-riscv.c (_bfd_riscv_relax_call): Always add max_alignment to
        foff.  If sym_sec->output_section and sec->output_section are the same
        and not *ABS* then set max_alignment to that section's alignment.
