[PATCH] tools: perf: Avoid error message when building with no python installed

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.
