The RPM .spec file would still have to know which packages should
not have the default optimizations overridden.
One solution would be a way for rpmbuild to define different sets of
optflags, which the .spec file could choose from (and if it chose an
undefined set the default set would be chosen instead). You could have
optflags-small, optflags-fast, etc., but if one wasn't defined for an
arch it would fall back to optflags.

I don't speak for anybody but myself - that's enough trouble.
