COMPMID-417: Add -fstack-protector-strong flag
The compiler seems to perform some "illegal" optimisations regarding the
stack pointer which cause valgrind to report invalid writes. (Or it
could be a compiler bug). Compiling with -fstack-protector-strong
generates "correct" code and thus allows to use valgrind.
