From 26b2fe3e5bfff38e941312edf4a6fe94a9e4dd43 Mon Sep 17 00:00:00 2001
From: Gregory Nutt <gnutt@nuttx.org>
Date: Sun, 7 Sep 2014 08:43:01 -0600
Subject: Changes to many Makefiles.  For kernel buil object containing main
 cannot go into library because of name collisions.  The object file must be
 handled as a special case in every Makefile
