Subject: [PATCH 3/3] cpupower tool: allow to build in a separate directory
This patch allows cpupower tool to generate its output files in a
seperate directory. This is now possible by passing the 'O=<path>' to
the command line.
This can be usefull for a normal user if the kernel source code is
located a in read only location.
This is patch stole some bits of the perf makefile.
