Unless we come up with some well-defined behaviour for handling binaries
(like file staging, etc.), I vote for adding a check in qsub to reject

Now that I think about it, executing binaries should already work?  The
default job launch mechanism is to echo the executable filename into the
login shell's stdin?  That should work correctly with a binary.

I'm thinking the actual default doesn't match ./configure's --help
