Only link with libdl on Linux
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.
