There is unfortunately a relatively large legacy base of existing
tools which depend on the device-tree (specifically, the
representation of the OF device tree that the kernel generates at
boot-time) present in proc, especially on platforms (PowerPC/Sparc)
which have a real OpenFirmware implementation.

On the other hand, since this is a new port, we can just assume that
(for this port) we're going to fix the tools to use a different path.
