It seems things are different these days. The problem is now simply one
of name mangling. libtool stores the module names unmangled in the
preload structure, but libltdl looks for mangled names.

E.g. I have the module "module-null-sink", which in the preload list is
as follows:

  {"module-null-sink.a", (void *) 0},

But looking in ltdl.c:try_dlopen() you'll see that it looks for the
mangled name "module_null_sink" with ".a" appended.

So either libtool needs to start mangling, or libltdl needs to stop.
I'm voting for the former as symbol names can already contain the
mangled module name.
