    build/riscv: tell the build system about riscv64/head.S
    
    This allows to `make arch/riscv/riscv64/head.o`.
    
    Example of rune on a fresh copy of the repository:
        make XEN_TARGET_ARCH=riscv64 CROSS_COMPILE=riscv64-linux-gnu- 
KBUILD_DEFCONFIG=tiny64_defconfig arch/riscv/riscv64/head.o
