Add support for compiling the host tools in the tools directory using
the MinGW toolchain.  This produces executables which can be used on
standard Windows computers without requiring cygwin.

One must specify the MinGW compiler and strip utilities as if they
were the host toolchain in order to build win32 executables, eg:

make HOSTCC=i586-mingw32msvc-gcc HOSTSTRIP=i586-mingw32msvc-strip tools

Compiling U-Boot in an old OS environment (RedHat-7.3  :-)  gives the
following warnings from FDT:

include/libfdt_env.h:50: warning: redefinition of 'uintptr_t'
/usr/include/stdint.h:129: warning: 'uintptr_t' previously declared here

Fix: Protect the definition of uintptr_t when compiling on the host
system.

On some systems (for example Fedora Core 4) U-Boot builds with the
following wanrings only:

...
In file included from /home/wd/git/u-boot/include/libfdt_env.h:33,
                 from fdt.c:51:
		 /usr/include/asm/byteorder.h:6:2: warning: #warning using private kernel header; include <endian.h> instead!

This patch fixes this problem.

This patch turns on the -Wpointer-arith option in the dtc Makefile,
and fixes the resulting warnings due to using (void *) in pointer
arithmetic.  While convenient, pointer arithmetic on void * is not
portable, so it's better that we avoid it, particularly in libfdt.

Also add necessary definition of uintptr_t needed by David Gibson's
changeset "dtc: Enable and fix -Wpointer-arith warnings" (the definition
comes from stdint.h, which u-boot doesn't have). -- gvb

Declare the variable fdt properly as extern.
Call the "set_fn" function pointer the "short way" without the full
  dereferencing syntax.

Changed _fdt_check_header() to fdt_check_header() and made it part of
the interface - it is a useful routine.

Also did some asthetics cleanup to the include files (headers).

Changes to David Gibson's original source to fit into u-boot's
environment.  No functionality changes.
