This was briefly discussed over on debian-devel. Would this something
Fedora might want to do, too?

This should not be enabled in the distro itself, and if, then not before it can
be enabled upstream. From my point of view it was a mistake to enable it this
way before getting this upstream. However it is a lot of work to get the
compiler to build itself with these flags and the testsuite produce the same
results as without these. In the past neither the Ubuntu security team nor the
Google ChromeOS team had time and resources to bring these patches upstream.
I agree we should stick with dpkg-buildflags until this is fixed upstream.
Gentoo Hardened tried to upstream this a year ago, but apparently this
didn't make
the cut yet:
http://gcc.gnu.org/ml/gcc-patches/2012-09/msg00473.html
As for the GSoC project; GCC partiticates, if anyone wants to push this,
I suggest
to talk to GCC developers and see whether there's a mentor available.
Cheers,
Moritz
