Ah, whoops, forgot about that. A select few packages get built i686 as well as 
i386, with the i686 build being preferred on capable systems -- those 
packages are glibc, openssl and the kernel, I believe. So just:

$ rpmbuild -bb --target i686 glibc.spec

(or rpmbuild --rebuild --target i686 glibc-*.src.rpm)
