Posix_GCC: update compiler options (#1227)

Browse source 
Posix_GCC: update compiler options

1. Add to CFLAGS
   - add -O0 optimization for debug builds.
   - add -O3 optimization for release builds. 
2. Update signal handler `handle_sigint()` to use
  `_exit()` instead of `exit()`. Normal exit() is not allowed
  within a signal handler.
