We came up with something similar last week. This is not actually
sufficient, but close. I will submit what I have to the U-Boot mailing
list soon (hopefully, later today), feel free to review it there and
import it to Debian.

Native builds don't seem realistic given the many different
architectures that U-Boot supports, unless done with virtualisation (see
my other email from today).

Now that I think about it, maybe virtualisation would require simply too
many VMs to setup.

Either way, we can always try to add a toolchain build script to U-Boot.
