OK, I found this bug.  Definitely make recursion was not being handled
properly with -Otarget and -Ojob in some situations; this broke as a
side effect of my cleanup to reuse the same temporary file for the
entire target, regardless of the output mode.

This should be fixed now.  Those who use recursive makefiles and were
seeing annoying delays in output with -O, please try again with the
latest commit and see if it works any better for you now.
