Switched to O3 with no inlining optim level for debug builds...

Switched to O3 with no inlining optim level for debug builds Debug builds are mostly used for gcov while it seems a bad idea(-O3), with O0 the FSW uses more than 100% CPU in normal mode so the treadoff is to switch to O3 without inlining, this preserves the 1 to 1 relation between code and gcov counters.
