The ARCH name in Linux for RISC-V is "riscv", but the toolchain tuples are "riscv64" and "riscv32". Arnd recently updated the crosstool builds at kernel.org to contain RISC-V toolchains, but without a small change to teach make.cross about the RISC-V tuple conventions this doesn't quite get glued together. This patch simply adds a rename rule for the RISC-V toolchains that are now availiable. This just always uses the riscv64 toolchain, as the only difference between the RISC-V tuples are the default march target (which Linux doesn't rely on) and, for non-multilib toolchians, what C library is installed (there's none on the binaries we're fetching).
