In a shell that allows you to say:

   make target >& logfile &

In this case, stdout defaults to fully buffered mode instead of
line buffered mode and with stderr being unbuffered, the fflush
is needed to make sure that anything written to standard out
appears in the output before the stuff written to stderr.
