Currently the script won't generate a configuration file that sets up qemu-user-riscv32 on riscv64, likely under the assumption that 64-bit RISC-V machines can natively run 32-bit RISC-V code.
However this functionality, while theoretically possible, in practice is missing from most commonly available RISC-V hardware and not enabled at the distro level. So qemu-user-riscv32 really is the only option to run riscv32 binaries on riscv64. Make riscv32 and riscv64 each its own family, so that the configuration file we need to make 32-on-64 userspace emulation work gets generated.
