--- Comment #1 from Kostya Serebryany <kcc at gcc dot gnu.org> ---
clang uses -whole-archive:
clang  -fsanitize=thread a.cc -v
 "/usr/bin/ld" -whole-archive
...lib/clang/3.5.0/lib/linux/libclang_rt.tsan-x86_64.a -no-whole-archive ...

I believe this is the only right thing to do. 
Placing the tsan run-time after the objects will have other nasty side effects 
(Alexey, Evgenyi may remember exactly which)
