Go 1.5: Cross compilation

Thank you for your post. It helped me to understand a little more cross-compilation in Go.

I was wondering if instead of pre-building the standard library for a given target we could simply copy the pkg/[target_arch] folder from an official go distribution into our pkg folder.

Also, you said “standard libraries builds are not preserved for future use at this stage”. So what’s the point pre-building? I’m confused
