But when I did my head -r319996 amd64 -> aarch64 cross build of
buildworld buildkernel I got no such errors:
# grep libc.so.7

I do use:
XCFLAGS+= -mcpu=cortex-a53
XCXXFLAGS+= -mcpu=cortex-a53
(but I've no direct clue if those make a difference).
The rest of what I do is rather generic.
Specifically I used:
