What did you do?

I tried to use unix.Time_t on a FreeBSD system:

package main

import(
        "fmt"
        "golang.org/x/sys/unix"
)

func main() {
        fmt.Println(*(*unix.Time_t))
}

What did you expect to see?

./time_t.go:9:14: type unix.Time_t is not an expression

What did you see instead?

./time_t.go:9:14: undefined: unix.Time_t

I'd like to take a pass at a fix if one isn't already underway,

@jharshman please feel free to send a fix

Change https://golang.org/cl/348012 mentions this issue: sys/unix: Add type Time_t to freebsd.

Haven't regenerated the files for arm and arm64. Not sure if this can be done without an emulator or without actually running the ./mkall.sh command on arm architecture.
