[PATCH v4 4/8] RISC-V: Recognize riscvNNbe* as target

[Marcus Comstedt]

bfd/
	* config.bfd (riscvbe-*-*, riscv32be*-*-*),
	(riscv64be*-*-*): Add target.

gas/
	* configure.tgt: (riscv64be*, riscv32be*, riscvbe*): Add them.
	(riscv*-*-*): Remove little endian override.

ld/
	* configure.tgt: Add riscvbe-*-*, riscv32be*-*-*, riscv64be*-*-*,
	riscv32be*-*-linux*, and riscv64be*-*-linux*.
