tests will need fdt type definitions provided in a subsequent patch
to libfdt_env.h. Since libfdt.h includes libfdt_env.h in the right
order anyway, just remove the fdt.h include.

This patch turns on a bunch of extra gcc warnings, most of which are
probably a good idea. Of the new warnings -Wnested-externs and
-Wstrict-prototypes need no code changes, we're already warning-clean.
The remaining one, -Wmissing-prototypes requires trivial changes in
some of the tests (making functions local).
This patch also rearranges the warnings flags into a separate make
variable for convenience, and turns on -Werror, to really encourage
people to keep the code warning-clean.

I've just tested building dtc as an x86_64 binary on a 32-bit i386
host by using:
make CC="gcc -m64"
This patch fixes a handful of minor bugs thus discovered:
* There is a printf() type mismatch on 64-bit in value-labels.c
* For the tests which use libdl, we were using the GNU make feature
where it will find libdl.so given a dependency in the form '-ldl'.
But this built-in make logic doesn't know we're compiling 64-bit so
finds the 32-bit version of the library. We avoid using this and
instead explicitly pass -ldl to CC, which being the 64-bit version
does know where to look.
* To process dtc's asm output into .so files, run_tests.sh was
directly invoking the (default instance of) the assembler and linker.
Instead invoke these via the CC driver, and allow that to be overriden
from the make environment.
* The x86_64 assembler doesn't 0 fill with the .balign directive
(presumably it is NOP filling). That doesn't produce strictly
incorrect trees, but it is confusing and confounds are testcases which
do byte-by-byte comparison of the trees produced by asm output with
direct dtb output (which does 0 pad where necessary, of course). This
patch uses the optional second argument to .balign to force gas to
zero-fill instead.

This patch adds a testcase using asm output mode to check that labels
within property values are correctly processed.
