I think in this case an entry in debian/rules that does check with
dpkg-architecture and turn the switches for this case is the best bet.

As you said yourself it only affects gcc 4.4, the only place that needs
the sourceful upload. Neither Debian testing/unstable nor Ubuntu oneiric
do have gcc-4.4 as default. It though would also affect Ubuntu
backports, that might be the only reason to get that into oneiric
indeed, to ease backports for them too.
Enjoy,
