I am working on a baremetal riscv toolchain using LLVM runtime and LLD linker. Baremetal.cpp provides most of the things needed for such toolchain. So I have modified it to also handle riscv64/32-unknown-elf targets alongside arm-none-eabi. Currently, targets like riscv64-unknown-elf are handled by RISCVToolChain which mostly expects a gcc toolchain to be present. If you dont want the dependency on gcc-toolchain/libgloss or want to use LLD, then RISCVToolChain is not a good fit. So in the toolchain selection code, I have made this dependency of RISCVToolChain on gcc toolchain explicit. It is created if gcc-toolchain option is present. Otherwise Baremetal toolchain is created. I will be happy to hear if there is a better way to choose between these two toolchains.
