Thanks

I played with that, and got to parallelize the checks with '-j2'.  On my 2-core machine the time 
to run the ObjC testsuite goes down from 1m45s to 57s when using '-j2' and executing the execute.exp
tests in parallel with the other ones (execute.exp itself takes 55 seconds so it's about the
best you can do with 2 cores).  It's good, but it's tuned only for '-j2' and the output is not too
great.  I wish DejaGNU was parallelizing the tests for us; it would be able to adapt much
better to changes in the argument of '-j', and could produce a nice report, identical
to the standard one.

Anyway, good enough for now.  A patch is attached below.

Ok to commit ?

Thanks
