[PATCH] selftests: intel_pstate: compile programs if executable not found

[naresh . kamboju]

From: Naresh Kamboju <naresh.kamboju@xxxxxxxxxx>

Test exit due to aperf.c: No such file or directory
./run.sh
gcc: error: aperf.c: No such file or directory
Problem compiling aperf.c.

The Makefile installs executable programs "aperf" and "msr"
so skip compile on target.
