MAINTAINERCLEANFILES in srcdir

[Stepan Kasal]

Hello,
  the target maintainer-clean contains
        -test -z "$(MAINTAINERCLEANFILES)" || rm -f $(MAINTAINERCLEANFILES)

which means that the files are cleaned only in the build tree.

But the files which are cleaned by maintainer-clean, but not
distclean, are usually distributed, because it is supposed that the
``special tools'' needed to created them are not available on the
user's machine.

Could we perhaps change the above command to:

        -test -n "$(MAINTAINERCLEANFILES)" && \
                rm -f $(MAINTAINERCLEANFILES) && \
                cd $(srcdir) && rm -f $(MAINTAINERCLEANFILES)

(I'm willing to implemement this eventually.)
