You should be able to use QEMU user-level emulation to run binaries from other architectures on a RISC-V system, while using native code for the rest. Alternately if the code is available and reasonably clean, you could try a RISC-V build yourself. (Obviously not for the JVM and other JIT-dependent stuff - though these ports are ongoing too - but for most smaller projects it should work fine.)
