As a check of the build process, I did download a pristine copy and it built with multiple jobs.
The copy that did not build cleanly is the one I've been updating all summer from the GitHub master, which is certainly not pristine. I did run a make dist-clean on it but that did not solve the problem. Is the fix from Trac 21672 supposed to solve the problem for existing copies or only a pristine one?
