[PATCH 3/3] externalsrc.bbclass: don't configure with --disable-dependency-tracking

[Andre McCurdy <armccurdy@gmail.com>]

One of the uses of externalsrc is to enable iterative editing and
rebuilding of source files during development. In such situations,
disabling Automake dependency tracking can lead to sources not being
rebuilt even though files they depend on have been modified.
