As far as I understand, the main effect is to call debian/rules with -j,
but it also set DEB_BUILD_OPTIONS (but I fail to see why).
Anyway, if the package continue to look to DEB_BUILD_OPTIONS, as the
make children could not communicate with the jobserver, some strange
results may appear. On architectures that have more than one flavour,
that just mean the number of jobs is actually (value of -j times number
of flavours).
