If you're just looking for PIE support, you don't need any overlays.
Just unmask gcc-4.3.3-r2:

echo "=sys-devel/gcc-4.3.3-r2" >> /etc/portage/package.keywords

Upon installing/upgrading the ebuild in question, you'll find that a
set of hardened specs are provided:

 [1] x86_64-pc-linux-gnu-4.3.3 *
 [2] x86_64-pc-linux-gnu-4.3.3-hardenednopie
 [3] x86_64-pc-linux-gnu-4.3.3-vanilla

If you're installing a system from scratch then, in my opinion, it is
a lot easier to rebuild a system seeded with a recent (vanilla)
autobuild stage than it is to use the hardened stages (which are still
based on gcc-3.4.6-r2 and usually stale in other respects).
