Add support for building native win32 tools

Browse Source 
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

$ CROSS_COMPILE=ppc_4xx-
$ export CROSS_COMPILE
Note: If you wish to generate Windows versions of the utilities in
the tools directory you can use the MinGW toolchain
(http://www.mingw.org). Set your HOST tools to the MinGW
toolchain and execute 'make tools'. For example:
$ make HOSTCC=i586-mingw32msvc-gcc HOSTSTRIP=i586-mingw32msvc-strip tools
Binaries such as tools/mkimage.exe will be created which can
be executed on computers running Windows.
U-Boot is intended to be simple to build. After installing the
sources you must configure U-Boot for one specific board type. This
is done by typing:
