I don't think that this is quite right when dealing with the snapshot. If the snapshot has one directory configured and the local installation has another, there will be a mismatch. We can guarantee that all snapshots are built with rustlib as the subdirectory.

I'm not sure if I understand this correctly. Doesn't CFG_ENABLE_LOCAL_RUST mean that the build process shouldn't use a snapshot?

Ah good point, I didn't look closely enough!
