This adds RISC-V into the build system enabling the following targets:
- riscv32-softmmu
- riscv64-softmmu
- riscv32-linux-user
- riscv64-linux-user
This adds defaults configs for RISC-V, enables the build for the RISC-V
CPU core, hardware, and Linux User Emulation. The 'qemu-binfmt-conf.sh'
script is updated to add the RISC-V ELF magic.
