We shouldn't be using environment variables for anything related to how things
are built; this should be a GN argument like anything else.

However, that can be fixed in a follow-up patch as long as we file a bug for
this.

Agreed. IMO the thing to do here is to make an actual GVC image target in GN and
just build that. This is just a literal transcription of what the previous
builder was doing.
