Well, glibc shoult be retro-compatible, so this should be needed only
if your applications are going to use those "new" syscalls (if any,
since most of the times the updates in the glibc are reduced to flags
and options to existing syscalls).

If you need to recompile the kernel only because of a missing/newer
module, you might not need to upgrade your glibc at all, especially
since all your applications already work fine with the glibc you
have... :)

Again, this is valid unless your application requires a specific
version of glibc to work correctly.
