Right, the proper way to use it would be call dlerror() before calling
dlsym. This makes sure that we see the right error. However, this
won't help with NetBSD's wrong implementation.

Recall that we also use dlopen et al. as interface to the respective
Windows functions. Thus this change is not trivial.

However, a better way to fix this is to get rid of dlopen. There is no
more need for idea-stub.c and we may add include IDEA support directly.
(That algorithm will probably never die - like Arcfour)
