It seems that you need symbols to debug threads.  I guess that gdb is
looking for variables to determine what threads/stacks are where.  It
cann't seem to get back traces without symbols in the 'libc', etc.

Have you stripped everything before you put it on your target? 

  http://sourceware.org/gdb/onlinedocs/gdb/Separate-Debug-Files.html

I found that on my ARM target, I could strip the libraries and use
'--add-gnu-debug-link' method.  I then can transfer the '.debug' files
when I have an issue and gdb will read them and suddenly, I can use the
pthread facility.

...probably not a CTNG issue.
