Log:
Silence an MSVC warning about testing a function for truth without calling it

In general, this is a reasonable warning, except real_pthread_create is
weak and can be null.  The existing usage is correct as it the function
is declared with SANITIZER_WEAK, but MSVC can't know that because it is
defined to nothing on Windows.
