Issue #8604: NetBSD does not provide libdl.

Browse source 
The dl*() functions are in libc directly. This probably applies to all
*BSD too. And from what I read, it should even apply to macOS, even
though a libdl is present there (is it bogus?).

So let's make the libdl check proper by only make it mandatory on Linux
(on Windows it was already unchecked too).
