Looks like support for '-fstack-protector-strong' was implemented in
more recent versions of gcc. The the URL below for details:

Thanks for the explanation. The blog says...
GCC 4.8.1 and the GCC version in Fedora 19 added another mode,
-fstack-protector-strong, bringing the number of stack protector
modes up to three.
Gentoo stable appears to be gcc-4.7.3-r1. ebuilds up to gcc-4.9.1 are
present in the tree. Upgrading gcc is painful, so I appreciate the
maintainers not forcing a rebuild with every version bump.
You don't need to upgrade. You can just install it in parallel with your
current GCC, and use the newer one just to build the kernel.
