From d7937773fd85daa675290816af981ff0079f21b8 Mon Sep 17 00:00:00 2001 From: Simon Dawson Date: Sun, 20 Jan 2013 11:55:41 +0000 Subject: avr32: support uClibc 0.9.33.2 Add a uClibc patch from OpenWRT, and tweak an existing patch to cope with the lack of a dup3 Linux syscall on avr32. This allow uClibc 0.9.33.2 to be built for avr32.
