[PATCH 2/2] Makefile: adding profiling option in Makefile

[Min He]

This patch added a option to control profiling on/off, by default,
profiling is on, so that VTune can be used to capture perf data from
SOS.
When running: make PROFILING=0, it will disable profiling and pmu will
be pass-thru and perf tools can be run directly inside UOS.
