fix(system): fixed -fstack-protector issue on P4

Browse Source 
During cpu_start stack-smashing would errorounsly trigger when compiled
with -Os on P4. This happened due to the stack canary value (stored in bss) changing when
we initialized bss and then getting flagged as a stackoverflow.

Disable fstack-protector for cpu_start to avoid this issue
