Posix_GCC: update compiler options (FreeRTOS#1227)

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. Signed-off-by: Florian La Roche <Florian.LaRoche@gmail.com>
