libfdt_env.h is missing in some stable installs (<1.3.0-3),
some released linux distributions(e.g. Ubuntu 12.04) depending
on it still complain missing libfdt even if already installed.
So give more detailed hint for such OS users.

"lost"?  Do you mean "lacks"?

If your libfdt-devel package lacks a required header, my advice would be
to use the DTC submodule, not to "fix manually" (whatever that means).

1.3.0-3 is an Ubuntu version, not an upstream one, isn't it?

We could just update the first line to say "libfdt not present or too old".
I agree with Markus that we should definitely not be suggesting
that users manually mess with trying to fix up their distro's package.
