further spurious dep-file rebuild fixes:

With the way dep-file generation was changed for LinkTargets in
8b5a984d, it is necessary to change all
other dep-file generation the same way, because the LinkTarget dep-files
are outdated wrt. the object dep-files after an initial make run, and
hence if any other dep-file depends in any way (even build-order) on a
generated Executable, say by depending on the corresponding target file,
then the PHONY entries in the outdated LinkTarget dep-files for the
executable and its linked libraries cause all these objects to be
recompiled.

It is not a problem that there is a rule with the dep-file as target,
and another rule for the corresponding actual target that writes the
dep-file as a side-effect, without dependecy between the targets:
because make does processing in 2 phases, first building all included
makefiles, second all other targets, it is guaranteed that the 2
commands don't race to overwrite the dep-file because (when there is no
dependency between them) they will not be executed in the same phase.

The only problem here is that this will probably make IDL processing a
lot slower on Windows, writing all those dummy dep-files.
