Hello,

the Debian riscv64 port is based on the Debian "unstable" suite
(i.e. Debian's development branch), so it usually follows
upstream's toolchain development rather closely.  Things will
slow down a bit during the next months, though, as Debian will
enter the staged freeze for the next stable release.

Debian doesn't have ready-made system images for riscv64 right
now.  Our plan is to provide a regular Debian-Installer image
for riscv64, but one of the last big blockers for that are
exactly the elfutils issues that Jim is trying to address in
this thread :-).

If you have access to a Debian/unstable system somewhere,
setting up a Debian-based riscv64 VM can be done rather easily. 
There is a step-by-step documentation in the Debian Wiki at

  https://wiki.debian.org/RISC-V#Setting_up_a_riscv64_virtual_machine

If you should happen to have further questions, feel free to
contact me.

Qemu works quite well (both user-mode as well as full-system
emulation).  Debian currently runs a large number of riscv64
package builders in qemu-system instances and they have shown
to be very reliable.
