From 9052b52dfc69d9567e2e664b0f096bfae535bcad Mon Sep 17 00:00:00 2001

Subject: Fix Debian bug #144306: pass target-specific variables into the
 environment properly.

Fix configure: allow cross-compilation; fix getloadavg (still needs _lots_
of work!)

Let $(call ...) functions to be self-referencing.  Lets us do transitive
closures, for example.
