I've just used 10.4-STABLE r329879 running inside VirtualBox 5.2.2
to build releng/11.1 r330038 plus this patch. Had to manually fix
single reject due to $FreeBSD$ mismatch in the sys/amd64/include/frame.h.rej

Otherwise, it builds just fine. And booted, too.

Not sure if there are other runtime tests needed.
