dpkg-buildpackage does support running a checker like lintian since
1.17.6 (see --check-command and DEB_CHECK_COMMAND in the man page).
Doing what you request would require running dpkg-genchanges twice,
but only sometimes, I'm not sure I like how that would smell as an
interface, but I'll ponder about it (maybe just adding an option to
request the filtering, so that the build type option is passed to
dpkg-genchanges for the final .changes file, but otherwise
dpkg-buildpackage performs a normal full build, hmmm).

What comes to mind though, although slightly cumbersome, is that right
now there's also this other option, which should cover all requirements
(except being succint :):

  $ export DEB_CHECK_COMMAND=lintian

  $ dpkg-buildpackage -us -uc
  $ dpkg-genchanges -g >../pkgname_version_src+all.changes
  $ debsign ../pkgname_version_src+all.changes

(dpkg-genchanges really needs a -O[filename] option, which I'll be
implementing soon, and signing should eventually be disabled by
default anyway as discussed some time ago here.)
