Fedora Core includes the updated glibc.  It is an entry in the ELF
auxiliary table put on the initial stack; the kernel uses it to convey
to glibc whether or not it should enable its secure mode.  This allows
secure mode to be enabled not only for setuid/setgid binaries but also
for other kinds of changes (e.g. capabilities, SELinux role/domain
changes, etc).
