Too l33t to read release notes?
There is no tls subdir since NPTL is the default (and LT is completely
gone in FC5). The code in /lib is the TLS code using the correct ABI.
The crippled ABI is supported by the code in /lib/i686/nosegneg. This
code is *automatically* used if the kernel is compiled to match the
glibc version. This happens using the
linux-2.6-xen-vdso-note.patch
patch in Red Hat's kernel RPMs.
