%{optflags} comes from the definition below and so that one change 
affects by intention *every* package build on this environemnt instead 
fiddle around in each and every spec file

[builduser at testserver:/rpmbuild/rebuild]$ cat /home/builduser/.rpmrc
optflags: x86_64 -m64 -O2 -march=sandybridge -mtune=sandybridge -fopenmp 
-mfpmath=sse -pipe -fno-strict-aliasing -fomit-frame-pointer 
-finline-functions -finline-limit=60 -fexceptions 
-fstack-protector-strong --param=ssp-buffer-size=6 -D_FORTIFY_SOURCE=2 
-Wstack-protector -Wformat -Werror=format-security
