+Fix pthread detection
+
+configure.in always calls AC_CHECK_COMP_OPT(pthread) which succeeds with the
+toolchain used although it does not contain thread support:
+
+checking for mutex_lock in -lthread ... no
+checking for pthread_mutex_lock in -lpthread... no
+checking for pthread_mutex_lock in -lc... no
+checking if compiler accepts -pthread... yes
+checking for pthread_mutex_lock in -lc... no
+checking for pthread_mutex_lock in -lpthread... no

+This positive configure check leads to

+using this defconfig
+http://autobuild.buildroot.net/results/e86/e86e97ff7887f1bdc6bf913498392ff50f56ea88/defconfig
+
+This patch disables the freebsd-only code path. Patching configure directly
+prevents the need for autoreconf.
