The libfdt overlay support introduces a bunch of new includes and functions.
Make sure we are able to build it by adding the needed glue.

Is this intended only for downstream u-boot only, or also for upstream libfdt?
If it's u-boot only, you don't really need the #ifdef UBOOT. If it's for upstream, then it shouldn't have u-boot specific stuff.
In general the environment into which you're embedding libfdt (u-boot in this case) should provide libfdt_env.h. The one included in upstream libfdt is essentially just an example version designed to work with POSIX userspace.
