 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 guess.

 I don't know either.
