[PATCH 3/4] Add machine-info to benchmark output

[Siddhesh Poyarekar <siddhesh at redhat dot com>]

Hi,

This patch adds a script that is invoked by the benchmark target to
print information about the machine the current benchmark is running
on.

	* benchtests/scripts/machine-info.sh: New file.
	* benchtests/Makefile (bench-func): Use it.
