Does

  CC=gcc-3.3 CXX=g++-3.3 dpkg-buildpackage

work? If not then the only way to do so is to provide
/usr/local/bin/gcc or ~/bin/gcc (before /usr/bin in the $PATH) to
call the appropriate one based on e.g. another environment variable.

Maybe it would be worth the create a new package which diverts
/usr/bin/gcc and /usr/bin/g++ and puts scripts into its place which
read and honour $DEBIAN_GCC_VERSION?
