Thanks a lot for all your help! Now I have a XEN-working libc6 debian
package. And it looks like most of my apps don't make problems so I
don't have to recompile them. Only mplayer and the nvidia-glx initscript
(what is not needed within a XEN domU of course) are triggering the tls
error message.

@Andy Lee
I had no problems rebuilding the libc6 package on sarge. Here is what I
did (maybe usefull for others, too):
# apt-get build-dep libc6
$ apt-get source libc6
Then I've edited the debian/rules file and added
'-mno-tls-direct-seg-refs' to both BUILD_CFLAGS and HOST_CFLAGS.
Then I did a
$ dpkg-buildpackage -rfakeroot
And voilÃ, after some time of compiling I got some debian packages as
expected. I've installed libc6 and libc6-i686 and put both packages on
hold so they are not updated.

Greetings,
Markus
