I noticed you filed a bug about this both for maemo:
https://bugs.maemo.org/show_bug.cgi?id=3479
And Debian:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=492702
Thanks!
There was a further comment about this issue in bug:
-----------------------------------
Do you have compat vdso support compiled in your kernel?
My guess would be that the linux-image-2.6.25-2-amd64 doesn't have that
support compiled in, thus using exclusively the randomized vdso which is
unsupported by the old glibc inside scratchbox.

My hopes are on the SDK+ project:
http://maemo-sdk.garage.maemo.org/
It should already work fairly OK for building ARMEL packages,
but currently it's tested/supports only Ubuntu Gutsy & Hardy.
