                    aarch64-linux-gnu
           Product: gcc
           Version: 5.0

$ go tool cgo -godefs types.go
unknown ptrSize for $GOARCH "arm64"

with a separately built go tool (1.2), built using gccgo-4.9, this works as
expected.

filing this as a regression for now.

$ cat types.go 
// +build ignore

package pty

import "C"

type (
        _C_int  C.int
        _C_uint C.uint
)

$ go tool cgo -godefs types.go
// Created by cgo -godefs - DO NOT EDIT
// cgo -godefs types.go

package pty

type (
        _C_int  int32
        _C_uint uint32
)
