From 9a7ca2ce530c59abcdccb8a730c53c6098b3da3a Mon Sep 17 00:00:00 2001 From: John Ogness Date: Mon, 28 Jan 2019 19:40:24 +0106 Subject: linking/hello: fixup Makefiles It is good to have Makefile and autotool versions for compare. But the Makefiles should not be intentially horrible. Clean them up to the level that we teach in the training.
