From 449880e0ffe528999c17f6ad6e4f87f1f4c46cdd Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 12 Apr 2017 09:02:30 -0700 Subject: [PATCH] busybox: Move libresolv detection to LEDE Makefile Since the LEDE nslookup applet is already specific to LEDE, move the libresolv detection into the busybox Makefile that LEDE uses. This fixes builds with external toolchains that don't automatically search for headers and/or libraries without being told so.
