tools: Remove the out-of-date MinGW support codes 

MinGW build for U-Boot tools has been broken for years. The official
support of Windows build is now MSYS2. Remove the MinGW support codes.

$ 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:
