Well my reason for looking at this was so that I could use Maxime's
git/svn patches to use a git repo to hold the U-Boot source.  As it
stands only Makefiles using gentargets can use this.  I would want to do
this for the linux kernel too.
Other details like ..._VERSION are not suited to the git/svn approach
either so I may just have to hack in the download part for my own
purposes.  If I think I have something that may be useful beyond that,
I'll post it.

Is this an inherent limitation of the make syntax or specific to the
layout of the buildroot makefiles?

I feared as much...
