The "build" command is most commonly used command, which is designed as a powerful wrapper for
"go build" command for convenience cross-compiling usage.
It provides much more features for building binary:
1. Cross-Compiling for many platforms and architectures.
2. Configuration file support for compiling.
3. Build-In Variables.
