buildroot config to generate error

Since uClibc can't be compiled with threads (bug 6224), it must be compiled
without thread support.

However then gcc-final can't be compiled because it cannoy find pthread.h:

In file included from buildroot/toolchain/gcc-4.8.0/libgcc/gthr.h:148:0,
                 from buildroot/toolchain/gcc-4.8.0/libgcc/libgcov.c:31:
./gthr-default.h:35:21: fatal error: pthread.h: No such file or directory
 #include <pthread.h>
                     ^
compilation terminated.
make[3]: *** [_gcov.o] Error 1
