Jim Wilson c6261a00c3 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.

	bfd/
	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.

	ld/
	PR 25181
	* testsuite/ld-riscv-elf/call-relax-0.s: New file.
	* testsuite/ld-riscv-elf/call-relax-1.s: New file.
	* testsuite/ld-riscv-elf/call-relax-2.s: New file.
	* testsuite/ld-riscv-elf/call-relax-3.s: New file.
	* testsuite/ld-riscv-elf/call-relax.d: New test.
	* testsuite/ld-riscv-elf/ld-riscv-elf.exp: Run call-relax test.
