Does the cross toolchain really work?

I successfully built the toolchain by using the instructions on the
hurd website.The package versions are
binutils 2.19 from cvs
gcc 4.3 from svn
glibc 2.7 from cvs
I use the toolchain to compile the hurd package,then copied
ext2fs.static to a Debian-Hurd machine.It doesn't work.I try to debug
it,gdb says the error is in __uselocale:32.I looked the code in glibc
locale/uselocale.c.I guess the error is something about thread or
tls.I know that glibc now can't compile without tls,So I compiled it
with '--without-__thread'.This time ext2fs.static seem to work
fine.But when I start my new hurd,It just stopped at 'exec'.I know if
everything works well,it will be "exec init proc auth".I don't know
how to debug the system, So I download a hurd livecd from
www.superunprivileged.org , boot the computer with it and mount the
hard drive to a directory.Both 'exec' and 'init' works fine using the
cd's glibc.So I changed 'LD_LIBRARY_PATH' to the new compiled glibc,it
says like 'cannot load shared library /mnt/myhurd/lib/libc.so.0.3
cannot handle tls'.I don't know if my way is right.
Why the static build program can work but the dynamic one can't?
I'm sorry for my poor English.
