Using parallel build (-jX) fails for us, so it takes ~13h to compile

dpkg-buildpackage does support -J in stretch (starting with dpkg
1.18.2).
But if -jN breaks, that's because the package is not parallel build
safe, so using -J will not improve things, as the package has not
opted in (or has opted out depending on the debhelper used) from
parallel builds anyway.
So what's the difference between setting DEB_BUILD_OPTIONS=parallel=n
and -Jn then? The former has some precedent in being set on build
daemons, so I'd assume that -Jn doesn't regress behavior here? Or is the
suggested interface the environment variable?
Kind regards and thanks
