cross-building ARM world on amd64

I've been following this guide ( in an attempt to build an armv6 world on my amd64 host running 10.0-RC4.

Using this command (inside /usr/src)
> # make TARGET="arm" TARGET_ARCH="armv6"  MAKEOBJDIRPREFIX=/usr/cross/obj buildworld

It eventually fails with:
> ./make_keys keys.list > init_keytry.h
> ./make_keys: Exec format error
> *** Error code 126
> Stop.
> make[4]: stopped in /usr/src/lib/ncurses/ncurses

Looking at the file in question, make_keys is an ARM binary, which obviously won't run on amd64, yet it is being executed.
I wonder what I'm missing here.

Also not quite sure what information would be helpful, but here's the host's uname -a output:
# uname -a
FreeBSD flap 10.0-RC4 FreeBSD 10.0-RC4 #0 r260130: Tue Dec 31 17:10:01 UTC 2013     root at  amd64

Thanks for any help,
