This is kind of the heart of the matter. libfdt is supposed to be
embeddeable into bootloaders and other weird and limited environments.
For this reason we can never directly include standard libc headers.
Instead *every* dependency of libfdt must be provided by libfdt_env.h
(which can be replaced depending on your build environment).
