Maybe the failure is due to this codex finding, which I copy-paste without editing:

[P1] New Docker image does not copy the crosstool-ng checksum patch.
Dockerfile:6 runs crosstool-ng.sh, but that script unconditionally reads /scripts/crosstool-ng-sha256-20260705.diff at crosstool-ng.sh:20. The existing RISC-V GNU image copies that file before running the script.

I'd missed this, as it is a recent change to resolve the fallout of kernel.org mirrors CDN being down for several days.

Added the appropriate COPY line to the Dockerfile and pushed, thanks for the suggestion :-)
