Dmitry Vyukov e2391f66f9 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

Sergey Matveev 69931c5841 [sanitizer_common] Add internal_clone(). 
Add a wrapper for the clone syscall for use in StopTheWorld. We
implement it only for x86_64, so stop building StopTheWorld for other platforms
(no one uses it outside x86_64 anyway).

See https://code.google.com/p/address-sanitizer/issues/detail?id=214 for why we
can't use the glibc clone() wrapper.

Alexey Samsonov acab30e927 Properly generate lists of exported symbols for sanitizer runtimes 
This change adds a Python script that is invoked for
the just-built sanitizer runtime to generate the list of exported symbols
passed to the linker. By default, it contains interceptors and sanitizer
interface functions, but can be extended with tool-specific lists.
