I originally had my laptop on a hardened profile (I think it was a
couple laptops back) but there were so many problems I eventually gave
up.  I remember doing a lot of system reinstalling as I switched
profiles around.  I don't have time to reinstall my system right now
so I'm trying to be sure I can switch to hardened (and from hardened
if necessary) without reinstalling.

Would 'emerge gcc glibc && emerge -e world' have the same affect?
