Here's a proposed patch that installs all of the standard Forth
files as part of ubldr on ARM.  It does not install a loader.rc,
however, so it should have no effect per se, other than putting
a few more files on the image.

I plan to commit this to the FreeBSD tree soon.

If you're using Crochet, I also just pushed a change to
Crochet so that it copies all the boot files provided by
FreeBSD's build, instead of just picking out the
ubldr and loader.help files.  With the FreeBSD patch,
this results in all of the Forth files actually being in the image.

Again:  A system built with these changes should
function exactly the same since loader.rc is still not
present.

To enable loader.conf, first boot the system, then:
  $ cp /boot/loader.rc.sample /boot/loader.rc
and reboot.

With these changes, I've built and booted a BeagleBone
image that does process loader.conf and seems none
the worse for it.

I still need to test on RPi; hope to do that this weekend.

This should be enough for people to start experimenting
with the beastie menu on RPi.  Just copy the loader.rc from
i386 and see what happens.  ;-)
