W: ccbuild source: debian-rules-ignores-make-clean-error line 39
N:
N:   A rule in the debian/rules file for this package calls the package's
N:   clean or distclean target with a line like:
N:   
N:    -$(MAKE) distclean
N:   
N:   The leading - tells make to ignore all errors. Normally this is done
N:   for packages using Autoconf since Makefile may not exist. However,
N:   this line ignores all other error messages, not just the missing
N:   Makefile error. It's better to use:
N:   
N:    [ ! -f Makefile ] || $(MAKE) distclean
N:   
N:   so that other error messages from the clean or distclean rule will
N:   still be caught.
