I don't consider this a good idea.  For example with AUCTeX I often do
a `make distclean' when aclocal.m4 or configure.in was changed.  I
wouldn't wanna let this delete my backup files.  Besides, it would
violate the guideline cited above as the files are not generated by
configuring or building.

Out of curiosity I looked at the Makefiles of autoconf and Emacs.  The
former does nothing about them and the latter has an extra target
`extraclean' for that purpose.
