It qemu cannot be compiled anyway so make sure we do not try to compile parts where the typechecker complains about on windows. Also all the e2e test files are only used on linux as well. pkg/machine/wsl also reports some error but to many for me to fix them now. One minor problem was fixed in pkg/machine/machine_windows.go.
