Re: Cannot compile aarch64 kernel from FreeBSD host

Hi!

Reviving this thread because there was no reply other than a private
one from Paul Goyette, and I found another reproducer.

I can reproduce this on NetBSD/amd64 by running

./build.sh -j 4 -N 1 -U -u -m evbarm64 tools kernel=GENERIC64

And I am puzzled because this is something that should work. Is "-m
evbarm64" the right value for 64-bit arm? I think so. FWIW, native
compilation works.
