Ok, then I'm confused because I'm seeing dumps just trying to run a null
program.  Unless there's NPTL setup stuff in crt0, I can't guess what
might be going on yet.  This same null binary runs on a qemu-system with
suitable rootfs & kernel.
    

The glibc startup code contains TLS initialisation that will fail on unpatched 
qemu. If you have applied the TLS patch there are a couple of other things 
that could cause problems:

- Make sure it's picking up the correct target shared libraries (or link your 
test application statically).
  

- Try configuring qemu with --static. The default (building qemu as a shared 
library) seems to cause strange problems on many systems.
  

- Make sure uname -r reports at least 2.6.16 (qemu can lie for you).
