becker33 f8657e3fd9 Propagate architecture information during concretization (#7412) ... This updates architecture concretization to * Search for the nearest parent in the DAG for architecture information rather than defaulting to the root of the DAG * Propagate architecture settings transitively, such that if for example the target is set at the root of the dag it will set the same target on indirect dependencies (assuming no intermediate dependency specifies a separate target). Previously this occurred in general but under some conditions did not, for example if an intermediate dependency specified some subset of architecture properties.		2018-03-21 18:14:01 -07:00
