Thanks for your report. Could you:

 (1) Make sure this error happens when you do a rebuild from scratch
     ("make clean all")

 (2) Post the .config, and the last ~200 lines of build output. The
     part of the error log you have copy/pasted is not sufficient to
     understand the issue.

Thanks!

Thomas
