Check again - dpkg-buildpackage now defaults to -Jauto (it sets DEB_BUILD_OPTIONS=parallel=n where n is the detected number of CPUs), on the basis that every Debian buildd already seems to set parallel >= 2, so any package that fails to build in that situation is already effectively unreleasable. (#842845) If you maintain packages where this can't work, use dh --no-parallel or put .NOPARALLEL: in your Makefile. S
