    app-misc/ola: do not use reinterpret_cast on NULL
    
    In C++, nullptr_t values generally cannot be converted to a pointer
    using reinterpret_cast. I say "generally" because glibc apparently
    lets it slide; musl on the other hand does not. Do it the proper way
    and use static_cast instead.
