tsan: fix linking when -ltsan is passed before -lpthread 

libpthread is weird:
/lib/x86_64-linux-gnu/libpthread.so.0:000000000000b9b0 T pthread_cond_init@@GLIBC_2.3.2
/lib/x86_64-linux-gnu/libpthread.so.0:000000000000c720 T pthread_cond_init@GLIBC_2.2.5
let's do it with @@ for now
we can always introduce more macros parameters later
