Added Makefile for building syborg-graphicswrapper using GCC
At present the build fails due to the following missing headers:
KhronosAPIWrapper.h
VirtualVideoInterfaceConstants.h
platformthreading.h
protocol_MGraphicsVHWCallback.h
@rem Used by the buildbot "clean" step.
call "%VS90COMNTOOLS%vsvars32.bat"
