Description

clang require @__tls_get_addr@ to be implemented on low level (libc) to support @__thread@ variables. Bionic doesn't provide it. GCC workaround it by using emulated TLS feature in libgcc. Clang don't support it yet, but "here":https://llvm.org/bugs/show_bug.cgi?id=23566 is corresponding ticket, with patches suggested.
