the reason why you are seeing this is that you're a naughty person and
not running "make check", where the second make invocation would rebuild
the LinkTarget .d files.

actually it makes a full build from scratch slower, expecially on
Windows writing thousands of .d files takes several minutes.

the advantage is that you can do a partial build; with the old way of
doing things every object file in every module was built to include the
.d file even when you only want something like "make comphelper.all".
