CMake: Set CMAKE_POSITION_INDEPENDENT_CODE instead of manual -fPIC

Browse Source 
If we are doing a statically linked build, there is no need for full
`-fPIC`, just `-fpie` is enough (which lets the compiler assume that
global variables can be accessed directly without the GOT, etc.). CMake
does the right thing already when we set the `POSITION_INDEPENDENT_CODE`
property.
