Shenghou Ma 5fbd6044bc syscall: workaround Dragonfly BSD kernel exec bug 
See also CL 4259056 for FreeBSD.

Test program:
// exec.go
package main
import (
        "log"
        "os"
        "os/exec"
        "runtime"
)
func main() {
        path := runtime.GOROOT() + "/src/pkg/net/http/cgi/testdata"
        cmd := &exec.Cmd{
                Path:   "test.cgi",
                Args:   []string{path + "/test.cgi"},
                Dir:    path
                Stdout: os.Stdout}
        if err := cmd.Start(); err != nil {
                log.Fatal(err)
        }
        if err := cmd.Wait(); err != nil {
                log.Fatal(err)
        }
}
