Commit 47508843 introduced a change in the dependency generation which breaks SPL, because the source files being built are not initially present and are symlinked as part of the build. The .depend file must depend not only on the files in the DEPS list but also on the sources which did not contribute files to the DEPS list, since these sources will otherwise not get a dependency and will not be built.
