Bernd, are you aware that Steffen has done exactly the opposite in
commit efc407da104b7882a8139b7ba4b1e2909dfded76?  Unfortunately, I no
longer can remember why he did the change (and there isn't an
explanation in the ChangeLog)...

Note that `RM' should be rather defined once in a top-level Makefile
and not many times in the various `Makefile.sub' files.

I think that from now on we should avoid such minor changes in the
build system, given that we are going to use the `automake' branch in
the near future.  As soon as time permits I will do a last release
from the current branch, so please try to help stabilize everything.
