In some build configurations the `libfdt.mk` file is included multiple
times. Due to the fact that rules cannot (or rather, should not) be
defined multiple times, the `MAKE_LIB` function (which this makefile
calls) cannot be called twice with the same inputs. Doing so leads to
warnings about overridden rules, e.g.:
lib/libfdt/libfdt.mk:19: warning: overriding recipe for target libfdt'

This change introduces an include guard to the file to prevent it from
executing twice. This avoids redefining the rules defined by `MAKE_LIB`.

TF Makefile was linking all the objects files generated for the
fdt library instead of creating a static library that could be
used in the linking stage.
