Subject: [PATCH] cmake: make "-no-pie" optional

The recent linux distros already support PIE so it shouldn't be a
problem to remove "-no-pie". To avoid issue#782, we make "-no-pie"
optional and enable it by default. For the distro with PIE luajit,
just add the following build option:

-DENABLE_NO_PIE=OFF

Then, bcc-lua will be built with PIE support.
