- Base Stack Check library for GCC/clang.

- Use -fstack-protector-all compiler flag to make the compiler insert the
- __stack_chk_guard "canary" value into the stack and check the value prior
- to exiting the function. If the "canary" is overwritten __stack_chk_fail()
- is called. This is GCC specific code.
