From 4b2c73ad056aa327dc3b505410da68cf384317ba Mon Sep 17 00:00:00 2001

Subject: [PATCH] Make backtrace support depends on execinfo.h existence
In some C-libraries (like uclibc), backtrace support is optional, so the
execinfo.h file may not exist.
This change adds the check for execinfo.h header and conditionnaly enable
backtrace support.
This issue has been triggered by Buildroot farms:
