ah, so WEBRTC_LINUX is defined for android... doh. Thanks for fixing.

This code btw is mostly derived from this (iirc):
https://cs.chromium.org/chromium/src/base/threading/platform_thread_posix.cc?...

   ret = gettid();
+#elif defined(WEBRTC_LINUX)
+  ret =  syscall(__NR_gettid);
 #else
   // Default implementation for nacl and solaris.
   ret = reinterpret_cast<pid_t>(pthread_self());
