From 8a14dab8bdad1d819924d6039b16061fccef3df2 Mon Sep 17 00:00:00 2001 From: Gustavo Zacarias Date: Mon, 12 Aug 2013 15:02:42 -0300 Subject: [PATCH] ltrace: disable libunwind for uClibc toolchains ltrace requires that libunwind is built with backtrace() support. For the internal uClibc toolchain we don't enable it, and for external uClibc toolchains we can't know. It's also unavailable for static uClibc toolchains. So just disable libunwind support for uClibc toolchains in general.
