+From a16012bf4ea63f714468d80ebe101481c917e4b8 Mon Sep 17 00:00:00 2001
+From: Peter Seiderer <ps.report@gmx.net>
+Date: Wed, 2 Dec 2015 00:22:26 +0100
+Subject: [PATCH] Adjust for buildroot build.
+
+ - enable CC override
+ - fix devLib/gpio include path for local build (without installing first)
+ - change CFLAGS from '=' to '+=' to honour buildroot given flags
+ - add linker name link for libwiringPiDev and libwiringPi for local linking
+   (without installing first)
+ - fix install linker name link (do not link with absolute path)
+ - add gpio-static linking target
