LDT use in LinuxThreads

[Ulrich Drepper]

I've enabled the use of the LDT-based thread descriptor for Liunx on
i686 by default now.  It works for me now and I've worked around the
problem in libgcc (they are using thread functions far too early) by
some special hack.

If it does not work for you please let me know about the kernel
version you are using.  In this case you can safely compile glibc for
everything below i686 since it won't use the new code.
