This comes handy when hacking with different cross compilers, some of which may or may not have _FORTIFY_SOURCE turned on by default. This patch allows us to turn _FORTIFY_SOURCE on by specifying --with-fortify option at configuration time (or to turn it off by specifying --without-fortify). If nothing is specified, default compiler behavior is assumed.
