[PATCH] tools: perf: Avoid error message when building with no python installed
From: Pawel Moll
Date: Mon Jul 27 2015 - 11:51:10 EST
When run on a system without a python interpreter installed, the makefile
probing python will try to execute
/bin/sh -c 'command -v -config [...]'
instead of
/bin/sh -c 'command -v python-config [...]'
resulting in the following error message:
sh: 1: command: Illegal option -c
Although harmless, the message can be quite confusing and hard to track.
