I have solved my problem. Doing a clean dry run of make on QGIS will fail, even when the non-dry run would succeed. If first running a successful "make", and dry running "make -n", the dry run will succeed.
Is that "normal"? I would consider it a kind of bug in the QGIS build code, but my understanding/experience is limited. I suspect that adding a '+' character to all the $(CMAKE_COMMAND) lines, and maybe to more lines as well, would fix this problem.
