Forgot to mention, the problem is only present on hardened. So it's probably something to do with _filter-hardened() in flag-o-matic.eclass.
This is the offending commit: http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/eclass/flag-o-matic.eclass?r1=1.185&r2=1.186 Reversing it fixes the issue: -fno-stack-protector-all is not added to klcc (-fno-stack-protector is still added, but klcc from stable dev-libs/klibc-1.5.20 supports it).
Short summary: Mike did some unreviewed changes to the eclass http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/eclass/flag-o-matic.eclass?r1=1.181&r2=1.182 http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/eclass/flag-o-matic.eclass?r1=1.181&r2=1.182 which broke compatibility for <gcc-4.7 and intel compilers see: bug 443778 and bug 445244 I tried to commit a fix but this let to this bug here. The whole thing needs to be fixed or reverted to original state. @qa Could you please supervise the changes made? @Mike Please fix this whole thing. I am sorry that my commit breaks something additionally, but broken things for stable packages.

this bug is not fixed. The eclass function does not work.
no one said this was fixed. it's a dupe of an existing bug. *** This bug has been marked as a duplicate of bug 445244 ***
