crossdev: disable SSP for freestanding/no libc targets
Otherwise, we end up with a mess like:
```
[...]
/usr/libexec/gcc/arm-none-eabi/ld: /usr/lib/gcc/arm-none-eabi/12/../../../../arm-none-eabi/lib/libg.a(libc_a-stack_protector.o): in function `__stack_chk_fail':
stack_protector.c:(.text.__stack_chk_fail+0x60): undefined reference to `_exit'
[...]
```
