Upstream LuaJIT v2.1 has no riscv64 backend, so fetch the plctlab v2.1-riscv64 branch on riscv64, with the recipe's patches rebased onto it, and drop the riscv64 COMPATIBLE_HOST restriction. Tested by building for qemuriscv64 (musl, clang) and running a JIT-ed loop under qemu-riscv64 (jit.status() is true).
