W debian-rules-uses-special-shell-variable

The rules file use the make variable $(_).

According to Policy 4.9, 'invoking either of make -f debian/rules <...> or ./debian/rules <args...>' must result in identical behavior'. One way to inadvertently violate this policy is to use the $_ variable.

If the rules file uses $(dir $(_)) to discover the directory containing the source package (presumably in order to implement the get-orig-source target), please replace it by $(dir $(firstword $(MAKEFILE_LIST))).
