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-ho=
st-2017-06-16:13:33:14 | more
Building =

Building /usr/obj/aarch64_clang/arm64.aarch64/usr/src/lib/libc/libc.so.7
I do use:
XCFLAGS+=3D -mcpu=3Dcortex-a53
XCXXFLAGS+=3D -mcpu=3Dcortex-a53
(but I've no direct clue if those make a difference).
The rest of what I do is rather generic.
Specifically I used:
