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.
