Because of this (from 
https://bugzilla.redhat.com/show_bug.cgi?id=975273#c3):

> [builduser at buildserver64:~]$ cat .rpmrc
optflags: x86_64 -m64 -O3 -march=corei7 -mtune=corei7 -fopenmp -mmmx 
-msse2 -msse3 -msse4.1 -msse4.2 -maes -pipe -fstack-protector 
--param=ssp-buffer-size=4 -mfpmath=sse -D_FORTIFY_SOURCE=2 -fexceptions

You're overriding the distro defaults and not including
%{__global_cflags} which a part of how the hardening flags (among all 
sorts of other distro defaults) get set for builds.
