On MinGW it is not possible to build shared and static libraries at once.
Add means to disable building the static libraries and fix a few issues with the MinGW build. All the hard work done by Alexander Strasser, minor changes by myself. Originally committed as revision 4909 to svn://svn.ffmpeg.org/ffmpeg/trunk
