Example .sh build scripts support WSL only, aka the only platform that doesn't matter here

These really should work on Mac/Linux too. Easy fix; I think the example shell scripts just need two adjustments:

• Add ".exe" extension to the end of the executable paths
• Call wine instead of directly trying to launch the Windows exes

It'd be best to confirm that the user isn't using WSL before trying to call wine, but I say that isn't strictly necessary (why would you use WSL instead of the native Windows scripts, anyway?) Still, would be nice, if possible.
