[Buildroot] dbg problem with threads

[Dominic Newton <dominic.newton@in-2-technology.co.uk>]

Check your target, I find uClibc's thread support for i386 can throw up 
some issues. Try compiling for something like i486 or i586 if your 
system can run that type of processor.

I've found this often solves all manner of thread problems, but I 
haven't tried this for gdb.
