"release" option result in error during execution

[chran554]

Describe the bug:

Using the "release" option gives an "flag provided but not defined: -src" error during build (package phase).

To Reproduce:

Cross package a fyne application on darwin (arm64) to either linux (arm64) or darwin (arm64) using "release" option.

Example code:

package main

import (
	"fyne.io/fyne/v2/app"
	"fyne.io/fyne/v2/widget"
)

func main() {
	application := app.New()
	window := application.NewWindow("Hello World")
	window.SetContent(widget.NewLabel("Hello World"))
	window.ShowAndRun()
}
