Now wanted to confirm with you whether these steps are correct or I need to follow
something else to build powertop binaries(in a linux machine) and then install it( in a
Android system).
that won't work... different C library for one
we have powertop running inside android builds internally, I would strongly suggest that
you contact the person
who is providing you with Android to get powertop included (quite often its only in
developer builds)
