As I can understand primarily this required for the allowing Fedora set 
of optimisation for current platform, for which package build. So, in 
case when maintainer add flags which is important fo building, 
performance, or changed as some workaround to bug - it is acceptable, 
but need comment. Otherwise, we MUST rewrite developer flags to fedora 
default %optflags.
