Comment (by herbygillot):

 So we should only display this where it is *absolutely* necessary, where
 (it seems) we are using Go with legacysupport.

 Secondly, it may make more sense to install a wrapper script that wraps Go
 rather than asking the user to set all of these environment variables
 themselves.
