Add configure option to enable GNU GCC stack smash protection.
This option is disabled by default because it is known not to work
on FreeBSD 9.1 and for Linux -> Windows cross compiling using the
Debian MinGW-w64 tool chain.
It is known to work for native compiles in Debian testing and
OpenBSD 5.2.
