Well, it goes on for a while and then stops. The last lines are:

  __xstat(/home/taneli/buildroot/home/user/XXX/configure.ac) -> (/home/taneli/buildroot/home/user/XXX/configure.ac)
  open(/home/taneli/buildroot/home/user/XXX/configure.ac) -> (/home/taneli/buildroot/home/user/XXX/configure.ac)

I can't tell if this is a good sign or a bad sign ...

Let me rephrase. Would this work (on N800), or am I going to
waste ummm... 10 minutes trying it myself:

% cp /bin/ls /media/mmc2/arm-lltc/bin
% chroot /media/mmc2/arm-lltc
% /bin/ls

(Supposing of course that /bin/ls is compiled against glibc2.3 or
whatever is in maemo3.0)
