From a173dfa93937d835b10f3b460faaa652a017f035 Mon Sep 17 00:00:00 2001 From: Bryan Hundven Date: Tue, 10 Nov 2015 15:09:20 -0800 Subject: uClibc: Fall back to default configs if not provided I've added the .config files to contrib/uClibc-defconfigs from buildroot to use as default configs if they are not provided in the sample. If a particular architecture really needs an option set, it should be either updated in the manange_uClibc_config function in scripts/build/libc/uClibc.sh or a custom ${uclibc_name}.config should be added to the sample (usually via `ct-ng saveconfig`).
