* depending on the android platform and ndk versions used, it may or may
* not be defined in libc.so. In the latter case, we fail to link. Defining
* it here as weak makes us provide the symbol when it's not provided by
* the crt objects, making the change transparent for future NDKs that
* would fix the original problem. On older NDKs, it is not a problem
* either because the way __dso_handle was used was already broken (and
