Details:

make 3.82 sometimes fails to make intermediate (or secondary) files during
parallel builds. I see that there are a couple bug reports with similar titles
but this particular bug seems to have been introduced in 3.82 (and is still
present in CVS).

I'm attaching a patch that adds a test that demonstrates the bug along with a
fix that seems to work. I'm not very familiar with the code so I'm not sure
that my fix doesn't break something else.
