lang/rust: Add riscv64 (riscv64gc-unknown-freebsd) support
A kernel with COMPAT_FREEBSD11 is required for now like on all other FreeBSD archs. FreeBSD11 never had riscv64 support, so GENERIC does not have it and a kernel rebuild is required. The same issue existed on powerpc64le. The riscv64gc-unknown-freebsd target was upstreamed and will be part of Rust 1.59.0 (2021-02-24).
