This bit is a bit problematic for building for arm64. Essentially we'd 
need a third category of compiler; native for the build machine (linux), 
cross target (win/arm64) and win32-cross for the native arch (for being 
able to build fxc to run it in wine).

Not sure how to solve this neatest... The original makefile in fxc might 
at least work if i686-w64-mingw32-g++ or x86_64-w64-mingw32-g++ happens to 
be available, regardless of what target is intended for the target of the 
whole build, but that's rather ugly as well.
