    FindThreads: Drop try_run to improve cross-compiling support · d4e551a9
    Steffen Dettmer authored
    Use `try_compile` instead of `try_run`.  It is not clear why `try_run`
    was ever needed, and it does not work during cross-compiling.
    Update the check's source file to remove code associated with actually
    running things.  Also remove the ancient `__CLASSIC_C__` code path and
    use a simple `int main(void)` as in `Modules/CheckIncludeFile.c.in`.
    Fixes: #16920
