What did you do?

I tried to build a project, but cgo code kept failing

code demo:

package main

import(
	"fmt"
	"gopkg.in/olebedev/go-duktape.v3"
)

func main()  {
	
	ctx := duktape.New()
	ctx.PushGlobalGoFunction("log", func(c *duktape.Context) int {
	  fmt.Println(c.SafeToString(-1))
	  return 0
	})
	ctx.PevalString(`log('Go lang Go!')`)
	
}

What did you see happen?

In command line:
go build -o main2 main.go
# runtime/cgo
In file included from _cgo_export.c:4:
cgo-gcc-export-header-prolog:31:14: error: size of array ‘_check_for_64_bit_pointer_matching_GoInt’ is negative

What did you expect to see?

compile fine when GOARCH is set to host arch, but fail when cross compile to arm64

what can I do to fix this inconsistent behavior?

Similar to this issue, but I believe I set the cross compiler correctly
#38693

that's an arm32 toolchain.
