For now, the corresponding output automake-1.14: object file(s) will be placed in the top-level directory.  However, automake-1.14: this behaviour will change in future Automake versions: they will automake-1.14: unconditionally cause object files to be placed in the same subdirectory automake-1.14: of the corresponding sources. automake-1.14: You are advised to start using 'subdir-objects' option throughout your automake-1.14: project, to avoid future incompatibilities.
