On some systems source fortification is enabled whenever code optimization is enabled (e.g. with -O2). Since code fortification is explicitly enabled too (with possibly different value than the system wants, there are three levels [1]), distros are required to patch our Makefile, e.g. [2].

Detect whether fortification is not already enabled and enable it explicitly only if really needed.
