When flashing loader.bin for K210 using kflash:

    [ERROR] This is an ELF file and cannot be programmed to flash directly: arch/riscv/boot/loader.bin

Before, loader.bin relied on "OBJCOPYFLAGS := -O binary" in the main
RISC-V Makefile to create a boot image with the right format.  With this
removed, the image is now created in the wrong (ELF) format.

Fix this by adding an explicit rule.
