build: Check for -fstack-protector-strong availability
Some compilers don't seem to support -fstack-protector-strong, let's make
it conditional.
$ gcc -fstack-protector-strong
gcc: error: unrecognized command line option ‘-fstack-protector-strong’
$ gcc -v
gcc version 4.8.1 (Gentoo 4.8.1-r1 p1.2, pie-0.5.7)
