There isn't really a big difference between IDF's toolchain and the one from Sifive, this is why we didn't add both. Are you having issues running the one from SiFive? The CROSSDEV variable will just have the name of the toolchain. If we want to add another toolchain we add another ifeq in riscv/rv32im/Toolchains.defs.
