I am cc'ing Morten Kristiansen.  We did manage to get things
linking recently.  I just posted a patch for newlib 1.17.0 for
the NIOS to the newlib mailing list.  You definitely want to
use 1.17.0 with the latest patches.

My full NIOS patches are at home.  Morten can help you
get things going.

The biggest issue you are facing is that the NIOS II binutils
version Altera uses is TOO old for the feature used in cpukit/wrapup.
Reverse this patch:

cvs diff -u -r 1.61 -r 1.62 cpukit/wrapup/Makefile.am

The librtemscpu.a is empty because of the old binutils. :)
