Lintian tag information: debian-rules-ignores-make-clean-error (type: warning)

Description (from lintian-explain-tags)

A rule in the debian/rules file for this package calls the package's clean
or distclean target with a line like:

-$(MAKE) distclean
or
$(MAKE) -i distclean

The leading "-" or the option -i tells make to ignore all errors. Normally
this is done for packages using Autoconf since Makefile may not exist.
However, this line ignores all other error messages, not just the missing
Makefile error. It's better to use:

[ ! -f Makefile ] || $(MAKE) distclean

so that other error messages from the clean or distclean rule will still
be caught (or just remove the "-" if the package uses a static makefile).
