    From my POV, it is up the author(s) of a specific piece of
    software to declare their code thread-safe.  Such info can
    then be tracked in a central document.  One can augment such
    a process by providing audit guidelines on how to approach
    the topic.

    Regarding automating the process - feel free and try to
    implement one.  The major hurdle is the filter lists you need
    to define for every possible C run-time environment /
    compiler combination, because each of those defines globals
    themselves.

    Here is an example output of nm for a dummy programm with two
    globals.  All symbols marked with [bBdD] are globals.
