Win fix

I don't know if this should be merged yet.

1. I modified the platform detection to check for any windows version of MINGW32.  It's working on at least two version of MinGW32, so that's promising?
2. Removed the libsorders.make and used config.win_cb.default.mk to order the libraries as @arturo suggested.
3. Removed zlib and strmbase from the windows PLATFORM_LIBRARIES.
