Depends on https://github.com/google/blueprint/pull/78 This uses the new CommandDeps field to move implicit dependencies embedded in the Command string next to the definition, instead of having to specify them in every BuildParam struct. This should make it easier to verify dependencies. Change-Id: I2711b160920e22fa962a436e1f7041272166f50f
