Hello genodians,
While building sculpt for virt_qemu_riscv, I found that dde_rump port is not prepared for RISCV. Taking help from the community, I used the same approach as for arm_v8a (aarch64) as found under "repos/dde_rump/lib/mk/spec/arm_64/*" just for "spec/riscv" in order to enable rump support for RISC-V.
I am getting this error. If you find it familiar, kindly help me

I looked into a lot of files and configurations but couldn't understand what am I missing. Kindly help me fix it.

Thanks & Regards,
