No, what I mean is: on platforms that do support shared libraries and packages that support static-only, they will still detect that dlopen() is supported and so they will still build support for dynamic libraries. But it's actually not a big deal, since they'll link with libdl.a so even at runtime everything will work.

I haven't tested yet. I don't know either.
