The output below seems ok, so I'm not sure why libc is failing. 1. I'm hoping you did a clean build (configure and make from scratch) of avr-libc? 2. What version of binutils are you using? 3. Can you try running make on avr-libc without -j5, just so that the error messages are a little more clear?
