link error messages

Hi all, 

I've attached the error messages, and let me also add Alexey's comments on this

__sanitizer::dtls variable has "initial-exec" attribute, and thus can't be
linked into .so.
It works fine as we don't link asan/tsan/msan runtimes into shared objects
(only into the executables), but it is not the case for UBSan.
