But when I did my head -r319996 amd64 -> aarch64 cross build of
buildworld buildkernel I got no such errors:

# grep libc.so.7 ~/sys_typescripts/typescript_make_aarch64_nodebug_clang_bootstrap-amd64-host-2017-06-16:13:33:14 | more

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:
