Bug 1289638 - Don't remove the SDK version from the SDK paths in the MSVC tooltool package. r=gps While we're here changing the MSVC tooltool package, and since we're going to remove the INCLUDE and LIB lines from mozconfigs that contain the SDK version, we might as well make the SDK in the tooltool package closer to an actual SDK, so that automation and local build more or less follow the same (upcoming) configure code path.
