virt-builder RISC-V edition

$ file builder/virt-builder
builder/virt-builder: ELF 64-bit LSB executable, UCB RISC-V, version 1 (SYSV), dynamically linked, interpreter /lib/ld.so.1, for 
GNU/Linux 2.6.32, BuildID[sha1]=184c9522f22abc5c325ac5a1ee2d272b225d5503, not stripped

Probably the least useful copy of virt-builder since there’s no qemu and no network. However it does demonstrate that we can now build large mixed C / OCaml binaries on RISC-V successfully.
