Details:

When make is run in parallel and one of the forked jobs fails, make stops
running additional jobs and waits for already spawned jobs to finish. If these
jobs take some time to complete and (even more important) generate much
console output, error most likely will get unnoticed unless one checks make's
exit code.

Would it be possible to print some error message at the point of master make's
termination in addition to returning with non-zero exit code? For a user it
would be much obvious indication that something bad happened earlier and one
should investigate output.

I think of something like this:

$ make -j24
...
<one of the jobs fails>
make: *** Waiting for unfinished jobs....
...
<lots of output>
...
make: Error <exit-code>  <--- Add message like this
$
