Add a makefile for cross-compiling on mingw. This builds win32 versions of the library and examples on linux using the mingw-gcc cross toolchain and wine. It also automates downloading and building the required dependencies. Update the _URL and _SHA variables to build against newer upstream releases. Thanks to Ron and Mark Harris for help with the makefile.

+= Cross-compiling under mingw =
+
+Just running 'make' in this directory should download
+and build opusfile and it's dependencies. Some mingw
+libraries need to be compiled into the final package.
+
+== Generic instructions ==
+
+To build opusfile under mingw, you need to first build:
+
+libogg
+libopus
+openssl
+
+For 'make check' to work, you may need wine installed.

+To build openssl, try:
