No, though I believe pushing GCC-5 into F22 was a mistake and pushing 
GCC-5 in to F23 at this point in time was a mistake, I also think it's 
too late to revert.

IMO, we have two alternative:
* "Close the eyes and pray", hoping there won't be any GCC-5 regressions 
which blow up F22 in a way, F22 will become unmaintainable/unfixable or 
will require a "partial mass rebuild" (E.g. because of hidden API/ABI 
changes or bugs).

* An F22 mass-rebuild, even though it is "this late in the cycle", even 
though this will likely cause a release delay and even though the 
persisting F23 GCC-5 issues will likely furtherly impact F22.
