FreeBSD (at least 7.2 to 7.2) calls nsdispatch(3) when it calls
getaddrinfo(3). And nsdispatch(3) doesn't call dlerror(3) even if
it calls _nss_cache_cycle_prevention_function with dlsym(3).
So our DL::Handle#sym must call dlerror(3) before call dlsym.
In general uses of dlerror(3) should call it before use it.

Linux and Darwin's RTLD_NEXT searchs second occurrence of the function.
But FreeBSD and NetBSD's RTLD_NEXT searchs in libraries loaded after dl.
