Bug#544530: lintian: wrongly reports build-depends-without-arch-dep

[Federico Gimenez Nieto <fgimenez@coit.es>]

Package: lintian
Version: 2.2.14
Severity: normal

In a package that uses dpatch (including the snippet /usr/share/dpatch/dpatch.make), debian/rules has:
  clean: unpatch

  clean-patched: 
          dh_testdir
          dh_testroot
          dh_clean

  unpatch: clean-patched

After building, lintian -iIEvXc --pedantic reports:

  I: libphp-pclzip source: build-depends-without-arch-dep debhelper

Changing the rules to:

  clean: clean-patched

  clean-patched:
          dh_testdir
          dh_testroot
          dh_clean
          $(MAKE) -f debian/rules unpatch

the information tag is gone.

Thanks,
Federico
