It turns out that simply commenting out lines 447-452 in /usr/src/Makefile.inc1 allows buildworld to run, even with no /etc/make.conf in place. This seems like a fairly reckless experiment, but having no better ideas, would anybody hazard a guess as to odds that the resulting userland might be expected to run? Are there any pre-install tests to be tried? At this point the kernel is at r324562, /usr/src is at r324599. Uname -p reports armv7.
