[ECOS] Running ECOS using the PPC simulator

[Ilan Ovadia]

The problem is while I'm running the bin_sem0 test
I don't get the message

PASS:<Binary Semaphore 0 OK>
EXIT:<done>

Actually, when I set breakpoints in the functions
located in bin_sem0 file, the debugger doesn't stop.
It seems like  ECOS doesn't succeed to complete
the initialization phase and run the test.

Regards
Ilan
