RISC-V: Segment fault for kernel purgatory when linking.

This was originally reported by Ard Biesheuvel <ardb@kernel.org>.

The followings are reproduce steps,

The segment fault happens in the riscv_elf_finish_dynamic_sections when the
output got section is an ABS.  Refer to MIPS code, they added an extra
bfd_is_abs_section check to avoid ABS got, so this seems the right and easier
way to go in the short-term.

bfd/
	* elfnn-riscv.c (riscv_elf_finish_dynamic_sections): Set sh_entsize
	and fill the got entries only when the got isn't an ABS section, and
	the size of got is larger than zero.  The similar goes for gotplt,
	except we already reported error when the gotplt is an ABS.
