From 5058a94ee717d96285da20423324af3478df175d Mon Sep 17 00:00:00 2001

Subject: Expand the loadable object support.

Provide a simple API for loaded objects to interact with GNU make.  I still
won't guarantee that this API won't change but it's much closer to something
that's supported and provides easy-to-use interfaces with a public header
file.
