RISC-V: Give error for ignored pcrel_lo addend.
bfd/
* elfnn-riscv.c (riscv_elf_relocate_section): Use bfd_reloc_dangerous
when pcrel_lo reloc has an addend. Use reloc_dangerous callback for
bfd_reloc_dangerous. Use einfo instead of warning callback for errors.
Add %X%P to error messages.
ld/
* testsuite/ld-riscv-elf/ld-riscv-elf.exp: Run pcrel-lo-addend test.
* testsuite/ld-riscv-elf/pcrel-lo-addend.d: New.
* testsuite/ld-riscv-elf/pcrel-lo-addend.s: New.
