+- <private/bionic_tls.h>: use kernel helper functions for static versions
+  of the C library. This is necessary because we don't know where the corresponding
+  machine code is going to run, and the optimization for __get_tls() might
+  not match the features of the target device where we run a static executable
+  linked to the C library. This fixes one of the bug that explains why gdbserver
+  didn't work well with threads.
