I committed parts of it:

The binary is expected to provide this symbol. This can't be fixed
without a large API change. Maybe for v2.1.

Also besides these, linking plugins will fail with those LDFLAGS. I'm
not sure about that .. seems wrong to have plugins also link to
libraries that the parent binary is required to be linking to anyway..
