Linux is (as far as I know) the only mainstream operating system that requires linking with libdl for dlopen. On BSD, libdl doesn't exist, so on non-FreeBSD BSDs linking will currently fail. On macOS, it's apparently just a symlink to libSystem (macOS libc), presumably present for compatibility with things that assume Linux. So the right thing to do here is to only add -ldl on Linux, not to add it for everything that isn't FreeBSD.
