see the official website to explain that the function is 
 to add a suffix to the directory where the package is installed to keep the output separate from the default version 
 I am testing that the function is 
 go build-installsuffix cgo 
 and does not add any suffixes, 
 such as 
 in src/test/main.go 
package main
import "fmt"
func main() {
    fmt.Println("hello world")
}
 what is the purpose of outputting files or test.exe 
 requests when go build-installsuffix cgo?
