FORTIFY_SOURCE is by far not the only thing that might make your
binaries require a "new" glibc. If you want to run against an old glibc,
you should build against such an old glibc. Example: NPTL threads. 
There are countless other examples of things that make your app require
a newer glibc *IF* you build against a new glibc.
If you don't want that.. don't do that then.
