Comment (by cjones051073):

 OK, what appears to be happening here is the rust/cargo build system
 doesn't propagate the environment variables to the processes it spawns for
 the underlying linking, and the wrappers rely on this to insert the legacy
 support flags. I'll have to see if there is an alternative option.
