tools/nolibc: Don't use stack protector before setting it up

Browse Source 
The stack protector is configured in _start_c() so we shouldn't
use it before then.

Add __nolibc_no_stack_protector to _start_c() to avoid the compiler
generating stack protector code for _start_c() and thus using it
before its configured.
