You can disable them on the command-line for any tool that builds
things, using the '--no-grafts' option, which is a "Common build option"
[0]. For example, `guix environment --ad-hoc go --no-grafts`.

If you do this, you should understand that the ungrafted Go package will
contain some serious security vulnerabilities, since we only use grafts
to fix vulnerabilities in core packages. [1]

We should figure out why this issue manifests when go is grafted, and
fix the root cause.
