It appears not :-/
Thinking about it some more we don't really need this for the sort of
default boot script I was thinking about, just a dtb -> dtb-$uname
symlink to match the vmlinuz/initrd.img ones is sufficient given the
ability to supply our own boot.scr, and flash kernel can arrange that
regardless of the packaged location.
I notice that the Debian powerpc packages use the same /usr/lib path as
the arm ones, I don't have the knowledge to go messing around with that,
which makes me inclined to leave ARM alone too rather than diverge
across the arches.

FWIW this new u-boot stuff include $fdtfile which is the file name, but
I don't think it includes (or cares about) the path to it.

Anywhere under /boot would do, wouldn't it? Debian and Ubuntu seem to be
the main ones which use /usr or /lib.
