Bug#860657: cppad: FTBFS on i386: dh_auto_test: make -j64 check ARGS+=-j64 returned exit code 2

[Barak A. Pearlmutter]

I'm always happy to have someone else upload a fix, just go ahead and do it.
But in this case, the latest upstream no longer manifests the problem.
Since there was no fix to the div.cpp test case, I suspect it was an
actual bug that the test case picked up and upstream fixed. But I have
not bothered to check.

Will close this big momentarily.
