From 84c93bb2fc4558a5e4654794ba90e730a84eaf67 Mon Sep 17 00:00:00 2001

Subject: Change altos build process to support per-product compile-time
 changes

This creates per-product subdirectories and recompiles everything for
each product, allowing per-product compile-time changes for things
like peripheral pin assignments and attached serial devices.
