+From 83b1d46ae48eed576cf3dff0ffd7e772c8e638e4 Mon Sep 17 00:00:00 2001
+From: Matt Weber <matthew.weber@rockwellcollins.com>
+Date: Mon, 9 Sep 2019 20:42:14 -0500
+Subject: [PATCH] Makefile: cleanup install
+
+Support the ability to rebuild and redeploy without a clean. This
+required some force linking and forced man archive creation.
+
+Provide the ability to override the stripping of the shared lib for
+cases where a embedded target build may want to control stripping
+or provide cross arch tools.
+
