Subject: [PATCH 4/4] perf tools: configure addr2line path at compile time

From: Irina Tirdea <irina.tirdea@...el.com>

The default name for addr2line is hardcoded to "addr2line".
When cross-compiling the name of addr2line will be different
(e.g. arm-eabi-addr2line in Android).

Setting the default addr2line name in the Makefile with PERF_ADDR2LINE_PATH.
