Well, there is.
Apply the Fedora patch for the problem:
http://pkgs.fedoraproject.org/cgit/glibc.git/diff/glibc-rh911307.patch?id=6cfdaac5b6b98b0810253d20e3cb4e069f432ec6
We could apply this for 2.18 as a band-aid to the gcc problem,
but it would need more massaging, like only enabling when configure
detects the transformation is present.
Cheers,
Carlos.
