Enable silent build rules for the NASM objects, if the source is configured with automake 1.11 or later. NOTE: the build still spits out "error: ignoring unknown tag NASM" for each object, but unfortunately, if we remove "--tag NASM" from the command line, the build breaks under older versions of automake (it aborts with "unable to infer tagged configuration.")
