Fix for config/sim.exp

[Steve Ellcey]

While looking at some GCC testsuite failures that were occuring while
testing with the qemu simulator I ran into a problem that I believe is
due to a missing override of sim_exec in config/sim.exp.

Basically the script in GCC (gcc/testsuite/lib/profopt.exp) was running:

        remote_file build delete $execname1

to remove a file and this was being translated into a rsh/ssh command
to my simulator baseboard as if it was a remote system.  After some
false leads I now believe that the problem is that config/sim.exp has
overrides for load, upload, and download, but no override for exec.

I made this patch to my dejagnu and now things are working, can this
patch be checked in to the dejagnu source tree?
