Consider (in Makefile.in):

install: [...]
        [...]
        -if [ ! -f $(sysconfdir)/Bla ]; then \
          $(INSTALL) -m644 $(srcdir)/Bla $(DESTDIR)$(sysconfdir)/Bla \
        fi

This is clearly a bug, most likely someone added DESTDIR later and
forgot it in the test. But unless that package build depends on itself,
you will never find it when building in a clean chroot.
