I think the problem is that the file toolchain\Config.in.2 is configured to 
only allow BR2_THREADS_NATIVE (NPTL threading option) to be selected if uclibc 
was set to the latest snapshot. This was a change made in February. It seems 
like this selection should also be allowed if glibc is the C library.
