Not sure if that's related to this change or an independent issue.

[DougGregor]

I'm fairly certainly this is an existing issue. SwiftPM isn't communicating to SwiftDriver which "swift" frontend executable to use, so SwiftDriver is looking for it relative to the just-built SwiftPM and not finding it. Fixing the hack I put in at https://github.com/apple/swift-package-manager/blob/3f55ea6d555ee8a73013eea44a50567fb69e9f41/Sources/Build/ManifestBuilder.swift#L208-L222 should address this... I think...
