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?
