Hurm.  It feels like there should be some easier way to do this.  It would
be nice if we could isolate more of the changes in the legacy packages
rather than making nvidia-graphics-drivers more obscure.

What if we copied all the nvidia-glx* files over to the legacy packages
as-is, rather than adding the -LEGACY suffix to every file in
nvidia-graphics-drivers, and then if $(legacy) is set, rename all files
matching nvidia-glx{,-dev,-ia32}.* and nvidia-kernel-source.* to add the
legacy version in the rules file?  That preserves the desire to keep the
file names the same in all packages, while having the file names be
"right" in the primary package.

This bit certainly seems fine.
