crossbuilding hints?

Hi all,

 trying to upgrade my Ultra 1E from 5.3-RELEASE to 6.0-STABLE.

 Since I hazard to guess that this would take a considerable
amount of time (to put it mildly) when built on this machine,
I decided to cross-build it on my main i386 machine.

 make buildworld TARGET_ARCH=sparc64 went fine.  After that,
I (naivetely) nfs-mounted /usr/src und /usr/obj from the i386
machine, but the installworld target failed because the install
toolchain (/usr/obj/usr/src/tmp/legacy/usr) are i386 binaries
(which makes sense).

 Can I nfs-mount the / and /usr filesystems from the Sun on my
i386 machine and then do an 'installworld DESTDIR=/mountpoint
TARGET_ARCH=sparc64'?  Is there a recommended method (read: 
documented) for doing this?
