From 02320931ce000836aa231ac1311769e303122099 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 14 Feb 2013 15:59:33 -0300 Subject: [PATCH] perf tools: Limit unwind support to x86 archs There's DWARF unwind support only for x86 archs, so limit the unwind.o object to them only. Without this building for other archs (e.g. cross compiling for ARM) is broken.
