Makefile: Disable stack protector due to gcc problems
Depending on how it was built, gcc will use the canary from a global
(works for us) or from the TLS (doesn't work for us and accesses
random stuff instead).
Fixing that would be tricky. There are talks of adding a gcc option
to force use of globals, but in the meantime, disable the stack
protector
