I've just tried it again using a git clone into a fresh directory and an
out-of-tree build similar to as you did above and I still get the failure:

Not sure if it's a contributing factor but my standard make invocation
tries to build with 2 cores once configure has run, i.e. "make V=1 -j2
install".
