i had a similar (or the same?) problem a while ago, the toolchain
generated code for armv5t, but my cpu was an armv4t.

martin guy kindly provided a patch that resolved the problem:
http://sourceware.org/ml/crossgcc/2008-05/msg00009.html

anyway i attach you a crosstool-ng .config using relativly up to date
components that is working for me. it uses OABI not EABI, but maybe it
can serve you as starting point.
