Even though the i686-pc-windows-gnu and x86_64-pc-windows-gnu tests are failing on AppVeyor, I believe this is a problem with the AppVeyor config.

On Ubuntu 18.04, I was able to build/test for the x86_64-pc-windows-gnu target by:

1. Installing toolchain/wine: apt-get install g++-mingw-w64-x86-64 wine
2. Setting ~/.cargo/config:

   [target.x86_64-pc-windows-gnu]
   linker = "x86_64-w64-mingw32-gcc"
   ar = "x86_64-w64-mingw32-gcc-ar"

3. Build test binaries:

   cargo test --target=x86_64-pc-windows-gnu
       Finished dev [unoptimized + debuginfo] target(s) in 0.12s
        Running target/x86_64-pc-windows-gnu/debug/deps/capstone-e3abe0e98ae3c2a7.exe
   run-detectors: unable to find an interpreter for target/x86_64-pc-windows-gnu/debug/deps/capstone-e3abe0e98ae3c2a7.exe
   error: test failed, to rerun pass '-p capstone --lib'
   

4. Run with wine:

   wine target/x86_64-pc-windows-gnu/debug/deps/capstone-e3abe0e98ae3c2a7.exe
