- `-go latest` will use the latest Go release - `latest` will use the latest Go release
- `-go 1.3.x` will use the latest point release of a specific Go version - `1.3.x` will use the latest point release of a specific Go version
### Output prefixing
Xgo by default uses the name of the package being cross compiled as the output
file prefix. This can be overridden with the `-out` flag.

### Build flags
A handful of flags can be passed to `go build`. The currently supported ones are
- `-v`: prints the names of packages as they are compiled
- `-race`: enables data race detection (supported only on amd64, rest built without)
