I think you are on the right track. What I would do:
- Keep the invocation of gl_LIBDL, but don't use the value of $(LIBDL)
in lib_LDFLAGS.
- Define _GL_USE_DLADDR only if $(LIBDL) is empty.
- Use the value $(LIBDL) to decide this, in the configure.ac section of the
module. I don't know whether that will require an Automake conditional.
