I agree that this is the sanest approach. And it's acceptable since it
will only last in precise... that said the precise packages are going to
last 5 years so it's quite likely that they will be used to build
much more recent packages (even if only backports).

Depending on how things evolve, it might make sense to also disable
it if Standards-Version ends up higher than a version of policy that
mandates dpkg-buildflags' usage (though I guess this is unlikely to happen
soon).
