The --target option may be what you are looking for:

rpmbuild -ba --target=i686 rpm.spec

You can replace i686 with what you need.

I noticed that a conditional in the .spec file could be used to add -march=i486 to CFLAGS and CXXFLAGS, if I wanted it to be self contained, but I like that --target solution better and I will go with that.

Thanks,
