Yes, it works with both clang and gcc.

That thread seems to be full of confusion. :-)  The base system is mostly
built with -fstack-protector, except for the ia64, arm and mips arches,
and for some specific cases where it is not necessary, or unwanted.

Ports are largely independent of the base system, and their compilation
flags are different from port to port.  You could set -fstack-protector
for your ports in either make.conf or ports.conf, if you wanted.
