With dpkg-buildpackage v1.21.10 or later, the only way to build the deb-pkg generated package parallely is adding -j<N> to the MAKEFLAGS environment variable or using the --jobs-force option. The package ignores the usual parallel build option that is described in Debian Policy §4.9.1. Derive make's -j parameter from the DEB_BUILD_OPTIONS environment variable that ends up being set by dpkg-buildpackage -j<N>.
